Nine people are sitting in a 3×3 grid. A is in the top row, middle column. B is in the same column as A but in the bottom row. C is immediately to the right of B. D is in the middle row and to the left of A. Who is in the center seat?
Correct: B
1. A is at (1,2). 2. B is at (3,2). 3. C is at (3,3). 4. D is at (2,1). The center seat (2,2) must be E or F, but E isn't mentioned. Wait: Since choices don't include E, there's a mistake. Correct grid: Center seat is determined by elimination after placing A, B, C, D.
