Establishing relative positions
Start with A right of B: [B, A]. E is left of B: [E, B, A]. C is right of A: [E, B, A, C]. D is left of E: [D, E, B, A, C].
Final Sequence and Position Check
The complete row is D, E, B, A, C. Counting from the left, B is the 3rd person, which is the exact middle of the 5-person row.
A: A is in the 4th position, not the middle. C: C is in the 5th position (right end). D: D is in the 1st position (left end).
B is correct because the arranged sequence D-E-B-A-C places B exactly in the third or middle position of the five-person row.
In linear seating, always place the person mentioned in the most clues first to anchor the arrangement quickly.
