Correct option is A
- A, B, C, D, E, F, and G are sitting in a circle playing cards.
- F is second to the right of G.
- B is a neighbor of F, but not a neighbor of C.
- E, who is a neighbor of C, is fourth to the right of G.
- D is between E and A.

So, A is to the left of G.
Thus, the correct answer is (a).
