A, B, C, D, E and F are sitting at a round table facing the center such that C is not the immediate neighbour of A. B is to the immediate right of C. If E and F exchange their positions, E will be the second to the left of A. D is the immediate neighbour of F. If D and E exchange their positions, who will be the second to the left of B?

C is not the immediate neighbor of A.
B is to the immediate right of C.
If E and F exchange their positions, E will be second to the left of A.
D is the immediate neighbor of F.
If D and E exchange their positions, Then we have to find second to the left of B.

After arranging the positions correctly and exchanging D and E in third figure ,

We find that D is second to the left of B.
Thus, The Correct option is (c) D.
