Therefore, statement alone is not sufficient to answer the question.

On combining statements, I and II:

I. E is sitting second to the left of D. D is sitting second to the left of A.

II. B is an Immediate neighbour of E. F is sitting between A and D.

Either B or C is sitting exactly opposite to A.

Therefore, statement I and II together are not sufficient to answer the question.

On combining statements, II and III:

II. B is an Immediate neighbour of E. F is sitting between A and D.

III. C is sitting third to the right of D and an immediate neighbour of E. A is sitting immediate left of C.

So, B is sitting exactly opposite to A.

Therefore, statement II and III together are sufficient to answer the question.

On combining statements, I and III:

I. E is sitting second to the left of D. D is sitting second to the left of A.

III. C is sitting third to the right of D and an immediate neighbour of E. A is sitting immediate left of C.

So, either B or F is sitting exactly opposite to A.

Therefore, statement I and III together are not sufficient to answer the question.

Hence, statement II and III together are sufficient to answer the question.
