The arrows show the opposite faces of the dice. The remaining two faces will also be opposite to each other in the dice.

Opposite faces cannot be seen adjacent to each other while we form the cube/dice.

Cube 2 cannot be formed because shaded part of the box is adjacent whereas it has to be opposite to each other.

Cube 3 cannot be formed as 2 opposite faces are made adjacent.

Now, only cube 1 and 4 are left. If we observe closely then we can see that in cube 4, circle with cross symbol is adjacent to the shaded face but in the unfolded cube it is adjacent to the face which is blank. Hence, cube 4 also cannot be formed from the given unfolded figure.

Now, only cube left is cube 1 that can be formed.

Hence, only cube 1 can be made from the unfolded cube (X).
