Correct option is A
Given:
Box A should be placed exactly three places above the box D.
Box C should not be kept on the top.
Only one box should be kept between the box E and box B.
Box E is at the bottom.
Position | Box |
5th | A |
4th | C |
3rd | B |
2nd | D |
1st | E |
So, Box C is in the 2nd position from the top.
Thus, correct option is (a).
