Show answer & explanation

Correct answer: C

1. Understand the Setup: There are seven friends (A, B, C, D, E, F, G) sitting in a circle, all facing towards the centre. Facing the centre means 'Right' is in the counter-clockwise direction and 'Left' is in the clockwise direction.
2. Place the First Condition: "F is to the immediate right of A." Let us place A at any position. F will be placed immediately next to A in the counter-clockwise direction (Right of A).
3. Place the Second Condition: "E is neighbour of A and D." For E to be a neighbour of both A and D, E must sit exactly between them. Since F is already occupying the immediate right side of A, E must be placed on the immediate left side of A. Consequently, D will be placed to the immediate left of E. Current arrangement section: D - E - A - F (moving counter-clockwise).
4. Apply the Third Condition: "G is not between F and C." We have 3 spots remaining for B, C, and G. The remaining open sequence next to F is: F -> [Spot 1] -> [Spot 2] -> [Spot 3] -> D. If we look at the arrangement, G cannot be between F and C. Let's place the remaining members to perfectly satisfy the circular flow. If we place C next to F, then the order becomes F -> C -> B -> G -> D. In this case, B is between C and G, and G is next to D. Let's check the position of G: Total circle position tracking (counter-clockwise): A -> F -> C -> B -> G -> D -> E -> A. Let's verify the condition "G is not between F and C": Here G is between B and D, which is perfectly valid. Question asks: "Who is sitting to the right of G?" Looking at the arrangement counter-clockwise (to the right of each facing-centre person), the person sitting immediately to the right of G is D.
