Reasoning

Concept: In design, architecture, and visual arts, scale refers to the size of an object in relation to a known reference, most commonly the human body. It helps in understanding proportion, usability, and visual harmony. Explanation:
Texture relates to surface quality, not size.
Scale is primarily concerned with how large or small an object appears when compared to human dimensions.
Height capacity of buildings is an absolute measurement, not a relative comparison.
Color scheme is related to aesthetics, not scale. Thus, the concept of scale is most clearly associated with the relative size of objects when compared to human dimensions.

Concept: This is an analogy based on the relationship between a material and the type of work or construction in which it is primarily used. Explanation:
Brick is the basic material used in masonry work.
Similarly, tiles are the primary material used in flooring.
Carpentry involves wood.
Wiring involves electrical cables.
Plumbing involves pipes and fittings. Thus, the correct analogy is:

Concept: This is a blood-relation puzzle that requires careful interpretation of family relationships, especially when indirect references are used. Step-by-step explanation:
The man says, \emph{“I have no brother or sister.”} Hence, his father’s son is himself.
He also says, \emph{“The father of the woman in the photograph is my father’s son.”}
Substituting from the first statement: The father of the woman is the man himself. Conclusion: If the man himself is the father of the woman in the photograph, then the woman must be his daughter.

Concept:
The required view is the orthographic projection in the direction of the arrow.
Only features directly visible from the arrow direction should appear.
Hidden edges and features not facing the observer are not shown. Step-by-step analysis:
The arrow indicates viewing the object from the front side of the fork-shaped opening.
From this direction, the following features are visible:
The semi-circular cut-out at the bottom (open towards the observer),
The circular hole in the upper block, visible as a circle,
A simple rectangular outer boundary.
The horizontal step seen in the 3D view is along the depth and hence does not appear as a dividing line in this projection. Comparison with options:
Option (A): Shows extra internal divisions not visible from this direction.
Option (B): Does not show the curved cut-out correctly.
Option (C): Shows an incorrect horizontal separation.
Option (D): Correctly shows:
The circular hole,
The semi-circular bottom cut-out,
No unnecessary internal lines. Hence, the correct view when looking in the direction of the arrow is Option (D).

Concept: When an object is divided vertically through its centre, a vertically symmetrical figure will have identical left and right halves. The odd figure is the one that does \emph{not} satisfy this condition. Step-by-step analysis:
Figure 1: The two small squares with diagonal crosses are placed diagonally. After vertical division, the left and right halves do not match. Hence, it is not vertically symmetrical.
Figure 2: The crossed squares at the bottom are arranged symmetrically about the vertical centre line.
Figure 3: The two crossed squares at the top are mirror images across the vertical centre.
Figure 4: The stacked crossed squares are centrally placed and remain identical on both sides after division. Conclusion: Only Figure 1 fails the vertical symmetry test. Hence, it is the odd one out.
Final Answer:

Concept: Colour psychology and light reflection play an important role in interior perception. Dark colours absorb more light, affecting how spacious a room feels. Explanation:
Dark colours absorb light instead of reflecting it.
This reduces brightness and creates a sense of enclosure.
As a result, rooms painted in dark colours tend to feel smaller and more confined.
Light colours, on the other hand, reflect more light and make spaces appear larger and brighter. Hence, a room painted with a dark colour will appear smaller than its original size.
