Step 1: Solving the four clues together (Q at position 1, M at position 3 from clue C; the O-T-P-R block placed with P at position 10 to avoid clashes, from clues A and D; then V, N and S fixed from clue B) gives the full seating from position 1 to 11 as: Q, W, M, V, N, U, S, O, T, P, R.
Step 2: S sits at position 7. Everyone to the right of S occupies positions 8, 9, 10 and 11, which are O, T, P and R respectively.
Step 3: Reading them in order from left to right gives O, T, P, R, which matches option 2.
