Correct option is D
Seven boxes A, B, C, D, E, F and G are kept one above the other, not necessarily in the same order. Box E is the topmost box.

Box G is the third box above box A. Box F is immediately above box G.

Box B is immediately below box C. There is only one box between box B and box D.


Three boxes (C, B, A) are there between D and G.
