Show answer & explanation
Correct answer: A
Final arrangement (left to right): B E G F D C A
Place B at one extreme and E next to B because B is at an extreme end and has E as his neighbor.
G is between E and F, so put G between E and F. With B and E placed, this gives the partial sequence B E G F.
C is immediately right of D, so C must be adjacent to the right of D.
D is third from the south end. Counting from the right end (south end) places D in the fifth position from the left, making the remaining seats D C A.
Combining all placements results in B E G F D C A, so the persons at the extreme ends are A and B.
Therefore, the persons sitting at the extreme ends are A and B.
