Select the dice that can be formed by folding the given sheet along the lines.

The Opposite surface of the open dice can be found by the below method:- 

• Alternate surfaces are opposite to each other.
• No two opposite surface are touched by side or by corners

So, by using the above rule we can find the opposite surface of open dice.

Below are the opposite surfaces shown :

Note :- Two opposite face are never seen together or adjacent to each other.

Given :

By option elimination method:

• Figures A and C cannot be two positions of the same dice. So, option 4 is eliminated. 
• Also, 4 and 6 will be adjacent to 1 if the question figure is folded to form a cube. So, either figure A or figure C has to be a part of the final answer. Thus, only option 2 satisfies this condition.

Hence, the correct answer is "Only B ,C and D".

Mistake Points

The question figure of unfolded dice can be represented as follows

The Figure A is as follows

As seen from above figures, the sequence in the Figure A is opposite to the sequence in the question figure.

Thus, the dice shown in Figure A can't be formed by folding the given sheet along the lines.
