Explanation:

- F is not on the extreme ends, so F can be in positions 2, 3, 4 or 5.

- A sits fourth to the left of F, which means there are three people between A and F. The only way to accommodate this is if F is in position 5 and A is in position 1.

- B sits second to the right of D, so D can be in positions 1, 2, 3, or 4.

- From the positions available, D can only be in position 3, making B in position 5.

- But F is already in position 5, so D must be in position 2 and B in position 4.

- C sits second to the right of B, so C is in position 6.

- This leaves position 3 for E.

- So, positions are: A (1), D (2), E (3), B (4), F (5), C (6).

- Who sits second to the right of A?

- From the seating order, E is in position 3.

- Option 2, E, is the correct answer.
