Solution
The correct options are
B A box
D A ball
A sheet of paper has length and breadth. Its height is very very small. The height can be ignored. Hence it cannot be a solid.
A box has all three dimensions, length, breadth and height. It is solid.
A refill will have only length since it's thickness and breadth are very small compared to its length.
A ball is solid. It has 3 dimensions.
Note: Technically, a refill and paper are solids. But since we have a condition that the dimensions must be significant compared to each other, they are not considered solids.
