Explanation:

- A is a neighbor of B and C.

- D is not a neighbor of C or E.

- G is second to the left of D.

- G is a neighbor of E and F.

To solve:

1. Arrange G such that it fits the scenario: G is second to the left of D and neighbors with E and F.

2. Place A between B and C since A is their neighbor.

3. Ensure D is not beside C or E.

Given that:

- The seating must fit a circular arrangement.

- D cannot sit between any positions that would put it next to C or E due to the conditions.

With the arrangements:

- Start with G and arrange it in such a way that D is correctly placed, with A, B, and C fitting the described conditions.

Thus, the person sitting third to the right of A is G .
