This question requires matching specific phonetic features listed in Column X with their corresponding Sanskrit terms in Column Y. Let's analyze each feature:
Combining these mappings gives us: P – 3, Q – 4, R – 2, S – 1.
The correct mapping derived is P – 3, Q – 4, R – 2, S – 1. This corresponds to Option A.

An ant is at the bottom-left corner of a grid (point P) as shown above. It aims to move to the top-right corner of the grid. The ant moves only along the lines marked in the grid such that the current distance to the top-right corner strictly decreases.
Which one of the following is a part of a possible trajectory of the ant during the movement?
A building has several rooms and doors as shown in the top view of the building given below. The doors are closed initially.

An art gallery engages a security guard to ensure that the items displayed are protected. The diagram below represents the plan of the gallery where the boundary walls are opaque. The location the security guard posted is identified such that all the inner space (shaded region in the plan) of the gallery is within the line of sight of the security guard.
If the security guard does not move around the posted location and has a 360° view, which one of the following correctly represents the set of ALL possible locations among the locations P, Q, R and S, where the security guard can be posted to watch over the entire inner space of the gallery.
