The correct answer is option 4 i.e. 
.
When the sheet is folded along the lines to form a cube, the opposite pairs are;
15 is opposite to 19. 16 is opposite to 17. 20 is opposite to 18.
In options 1, 2, and 3 the opposite pairs (20,18), (15, 19), and (16, 17) are adjacent to each other respectively.
In option 4, no opposite pairs are adjacent to each other. Hence, this cube can be formed.
