Show answer & explanation

Correct answer: A

Key observations:

  • L and K sit at the two ends.

  • G is immediately right of F, so F and G form an adjacent block F-G with G to the right of F.

  • "Only G is between F and K" means G is the single person between F and K. Since G is immediately right of F, K must be immediately right of G, making the contiguous block F-G-K and placing K at the right end.

  • Place K at position 6 (rightmost), then G at 5 and F at 4. L is the other end at position 1. The remaining positions 2 and 3 must be J and H with J immediately left of H, so position 2 = J and position 3 = H.

Final arrangement (left to right): L J H F G K

Therefore F is 4th from the left.
