Step 1: Define Per Capita Income.
Per Capita Income (PCI) is a measure of the average income earned per person in a given area (city, region, country, etc.
) in a specified year.
It is calculated to understand the average economic well-being of the population.

Step 2: Recall the formula for Per Capita Income.
Per Capita Income is calculated by dividing the total national income (or sometimes Gross Domestic Product - GDP, or Gross National Income - GNI) of a country by its total population.

Step 3: Match with the given options.
Option (3) "National Income Population" correctly represents the formula for Per Capita Income.
This matches option (3).

Step 1: Define the terms related to national output and development.

Step 2: Match the definition with the given phrase.
The phrase "An increase in a country's real output of goods and services" directly defines economic growth.
