Concept:Solve by placing people from left to right using fixed end positions and neighbour clues.
Explanation:A and P are at the two ends.
R is immediately left of A, so A must be at the right end and P at the left end.
Thus P is at the left end, and R is next to A at the right end.
S is seated second to the right of P, so S is two places away from P.
Z is a neighbour of both S and R, so Z sits between S and R.
The only remaining position is for X, which is immediately to the right of P.
Final arrangement is: P, X, S, Z, R, A.
Answer:X is seated to the immediate right of P.
Correct option: B. X
