The correct answer is

E

Number the positions 1 (bottom) to 7 (top). G is third from the bottom, so G is at position 3.

Only two boxes are kept between G and C, so C is either at position 6 (above G) or position 0 (below G). Since position 0 does not exist, C is at position 6.

“Only F is kept below B” means exactly one box lies below B, so B is at position 2 and F is at position 1.

Remaining positions 4, 5 and 7 are to be filled by A, D and E, with E immediately below A. The only valid placement is A at 5 and E at 4, leaving D at position 7.

Final order from top: 7-D, 6-C, 5-A, 4-E, 3-G, 2-B, 1-F.

The fourth box from the top is at position 4, which is E.

Hence, the box fourth from the top is E.
