2) E is not an immediate neighbour of either A or F.

From the above statements, we can determine that A and F are sitting at the second positions from either end, but not particularly in that order. This further implies that E is not sitting on the first three seats from either end, which leaves us with only one option i.e. the middle seat.

3) E sits third to the left of B.

This means that B is sitting at the extreme right end.

4) B is not an immediate neighbour of A.

So, A is not sitting in the second position from the right end. This means that F is sitting there and A is sitting at the second position from the left end.

5) Only two people sit between A and G.

This is only possible if G is sitting to the immediate right of E.

6) E is not an immediate neighbour of C.

This means that C is sitting at the extreme left end as he can't sit next to E. This further implies that D is sitting between A and E.

Clearly, B and C are seated at the extreme ends of the line.
