Final answer:
In a regular hexagonal seating arrangement, the person sitting opposite to friend P is friend T when all friends are seated in sequence around the table.
The correct option is d.
Step-by-step explanation:
The subject of the question is Mathematics, specifically geometry involving shapes and their properties. The question seems to be asking which friend is seated opposite to friend P at a hexagonal table.
To answer this question, it is not needed to have the information in the provided answer concerning chemistry, which seems to be mistakenly given and irrelevant to the question at hand. In a hexagon, the corners are directly opposite to each other when they are three edges apart.
Therefore, if you label the six friends as P, Q, R, S, T, and U in a clockwise or counterclockwise direction around the hexagon, the friends directly opposite each other would be: P opposite to T, Q opposite to U, and R opposite to S.
Based on this seating arrangement, the correct answer would be (d) T - because T is the one who would be seated opposite to P in a regular hexagonal table if the friends are seated in sequence.
The correct option is d.
