Show the answer and explanation
Correct answer: A
Explanation
Row facing north: left is west, right is east. Row facing south: left is east, right is west. Each person faces the one in the same position of the other row.
Row 1 faces north, so its right end is east: Q is at the east end and R beside him (fourth from the west). T is in the middle. S is not next to T, so S is at the west end and P second.
A faces T (middle of Row 2) and D faces R. B is second to A's left; left is east for Row 2, so B is at the east end. E is not at an end, so E is second from the west and C is at the west end.
West to east: Row 1 S, P, T, R, Q; Row 2 C, E, A, D, B.
E faces south, so E's left is the east side: the next seat east is A's.
Worth noting
C is E's neighbour on the west, which is E's right. B is at the far east end, two seats beyond A.
