Explanation:

- F sits at the extreme left end of the row.

- G sits second from one of the ends, which places G second from the right (as F is on the extreme left and is already occupied).

- E has an equal number of persons on either side, putting E in the fourth position from the left.

- There are three persons between F and B, so B is fifth from the left.

- A sits immediately right of C, and A does not sit at the corner, placing C in the second position from the left and A in the third.

- The arrangement from left to right: F, C, A, E, B, G, D.

- There are five persons to the left of G: F, C, A, E, and B.

Option 2: Five is the correct answer.
