How does the shape (X) below look like when folded in?

A)  B only                    

B)  A, B and C only

C)  A and B only                     

D)  A, B, C and D

Correct Answer: A

Solution :

  When a cube is formed by folding the sheet shown in figure (X), then  is one of the faces of the cube and this face lies opposite to a blank face. Also, a face bearing a circle lies opposite to one bearing a dot. Clearly, this cube does not have faces as shown in the cubes in figures [c] and [d]. Hence, only the cubes shown in figures [a] and [b] can be formed.
