Answer: A. D

Answer: A) D
Explanation: Set C in the middle (position 4). D and E must be at 3 and 5. Since B is the immediate right of E, the order is D-C-E-B. Remaining are A, F, G. Since A is not at the end, A is at 2, F and G are at 1 and 7. Since F is not neighbor to D, F must be at 7, and G at 1. Final Order: G-A-D-C-E-B-F. D is immediate left of C.
