Show the answer and explanation
Correct answer: B
Explanation
S is fourth from the right: fifth from the left. V is two seats clear of S and not at an end, so V is second and Q, on V's right, third.
T is at an end with U two places to T's left. At the left end there is no seat to T's left, so T is eighth, U sixth, and P (immediately left of T) seventh.
Seats 1 and 4 remain. W is not at an end, so W is fourth and R first.
Counter, left to right: R, V, Q, W, S, U, P, T.
Q is third and U sixth; W and S sit between them: 2.
