Step 1: Understanding the question.
The question asks about the state with the lowest population density in India. Arunachal Pradesh, due to its hilly terrain and less developed infrastructure, has the lowest population density among Indian states.
Step 2: Analyzing the options.
(A) अरुणाचल प्रदेश: Correct — Arunachal Pradesh has the lowest population density in India.
(B) असम: Assam has a higher population density compared to Arunachal Pradesh.

Step 1: परिभाषा।
महान विभाजक (Great Divide) वह वर्ष है जिसके बाद भारत की जनसंख्या निरंतर वृद्धि-पथ पर आ गई और उससे पहले उतार-चढ़ाव (यहाँ तक कि ऋणात्मक वृद्धि) देखने को मिला।
Step 2: तथ्य।
1911–1921 दशक में भारत ने ऋणात्मक वृद्धि दर्ज की; 1921 के बाद से प्रत्येक दशक में जनसंख्या लगातार बढ़ी—इसीलिए 1921 को Great Divide कहा जाता है।
Step 3: विकल्प जाँच।
(A) 1951: स्वतंत्रता-उपरांत पहला जनगणना वर्ष, पर Great Divide नहीं।
(B) 1931: 1921 के बाद का दशक है; सही नहीं।
(C) 1921: सही — यही Great Divide वर्ष है।
(D) 1971: जनसंख्या तीव्र वृद्धि का काल, पर Great Divide नहीं।
Step 4: निष्कर्ष।
उत्तर (C) 1921 — भारत की जनगणना में इसे Great Divide कहा जाता है।

Step 1: Understanding the question.
This question is asking about India's rank in terms of population in the world. India is the second most populous country after China.
Step 2: Analyzing the options.
(A) पहला: This is incorrect, as China holds the top position in population.
(B) दूसरा: Correct — India is the second most populous country in the world.
(C) तीसरा: This is incorrect, as India is second, not third.
(D) चौथा: This is incorrect, as India ranks second.
Step 3: Conclusion.
The correct answer is (B) दूसरा, as India is the second most populous country in the world.

Step 1: Understanding the question.
The question is asking about the percentage of the world's population that resides in Asia. Asia is the most populous continent, with more than 60% of the world's population.
Step 2: Analyzing the options.
(A) 40 प्रतिशत: This is incorrect; Asia has more than 40% of the global population.
(B) 60 प्रतिशत: Correct — Approximately 60% of the world's population resides in Asia.
(C) 50 प्रतिशत: This is incorrect; the correct percentage is higher.
(D) 25 प्रतिशत: This is incorrect, as the percentage is much higher.
Step 3: Conclusion.
The correct answer is (B) 60 प्रतिशत, as around 60% of the global population resides in Asia.

Step 1: Understanding the question.
Age structure refers to the distribution of a population across different age groups. This is a critical factor in demographic studies. Step 2: Importance of age structure.
1. आर्थिक विकास (Economic Development): Age structure influences the workforce and labor productivity. A younger population can contribute to economic growth, while an aging population can create challenges.
2. स्वास्थ्य सेवाएं (Healthcare Services): The age structure impacts the demand for healthcare services, with younger populations needing more maternal and child health services, while older populations require more care for chronic diseases.
3. शैक्षिक सुविधाएँ (Educational Facilities): An age structure with a high proportion of children requires more schools and educational resources.
Step 3: Conclusion.
The age structure of a population is vital for planning resources, infrastructure, and services. It affects everything from employment to healthcare and education.

Step 1: Understanding the 2011 Census.
The Census of India 2011 recorded the total population of the country as approximately 121 crores (1.21 billion). This included both rural and urban populations across all states and union territories.
Step 2: Analyzing the options.
(A) 121 crores: Correct. It matches the official figure from the 2011 Census.
(B) 125 crores: Incorrect. This figure represents an estimated population after 2013.
(C) 130 crores: Incorrect. This number reflects India’s estimated population around 2015–2016.
(D) 135 crores: Incorrect. This figure corresponds to India’s approximate population in 2019.
Step 3: Conclusion.
Therefore, as per the 2011 census, the population of India was 121 crores.

Step 1: Understanding urban population data.
According to the 2011 Census, about 31.16% of India’s population lived in urban areas. The remaining population, around 68.84%, resided in rural areas.
Step 2: Analyzing the options.
(A) 31.16 per cent: Correct. This is the official figure from the Census of India 2011.
(B) 30 per cent: Incorrect. This is a rounded estimate, not the precise figure.
(C) 35 per cent: Incorrect. This was the approximate urban percentage projected after 2016.
(D) 40 per cent: Incorrect. India’s urban population had not yet reached this proportion in 2011.
Step 3: Conclusion.
Thus, the urban population in India in 2011 was 31.16 per cent.

The density of population refers to the number of people living per unit area, usually measured in persons per square kilometer. It helps to understand how crowded or sparsely populated a region is.
Step 1: Definition.
Population density is calculated as: Step 2: Purpose.
It shows how human population is distributed in different regions. High density means more people in a small area, while low density means fewer people spread over a larger area.
Step 3: Example.
For example, states like Bihar and West Bengal have a high population density, whereas Arunachal Pradesh and Sikkim have a low population density.
Step 4: Conclusion.
Hence, the density of population is an important indicator for planning resources, infrastructure, and services in any country.

Step 1: Understanding the question.
The question asks for the major factors responsible for population change — i.e., the increase or decrease in population size over time.
Step 2: Explanation.
Population change occurs due to three main components:
1. Births (Natality): Increase population size.
2. Deaths (Mortality): Decrease population size.
3. Migration: Movement of people between regions — can increase or decrease the population of an area depending on inflow or outflow.
Step 3: Conclusion.
All three — birth, death, and migration — are components of population change. Hence, the correct answer is (D) All of these.
