Show answer & explanation
Correct answer: C
Number the eight seats clockwise as positions 1 to 8. Let the corner seats be 1, 3, 5 and 7, and the middle-of-side seats be 2, 4, 6 and 8. Corners face outside; middle seats face inside.
Assume Q is at corner position 1. Since Q is third to the right of K, K must be at position 6. K is at a middle seat and faces inside, so K's right is clockwise: 7, 8, 1.
P is second to the left of K. For K at position 6 facing inside, left is counter-clockwise, so P is at position 4.
P is immediately right of S. If S is at corner position 5 and faces outside, S's right is counter-clockwise, which is position 4. So S is at position 5.
K and D are facing each other. The seat opposite K at position 6 is position 2, so D is at position 2.
A is not at a corner, so A takes the only remaining middle seat, position 8. G and M occupy the remaining two corner seats in either order. This G/M interchange does not affect the answer.
Q is at position 1 and faces outside. For a person facing outside, the immediate left is clockwise. The clockwise seat from position 1 is position 2, occupied by D.
Therefore, the person sitting immediately left of Q is D. The correct answer is Option C.
