Select the dice that CANNOT be formed by folding the given unfolded paper.

Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2.
After folding the sheet along the lines;
b is opposite to f
a is opposite to c
d is opposite to e
From the second option, 'd' is adjacent to 'e' which is not correct to form a dice as opposite pairs can never be adjacent. Thus, option 2 cannot be formed.
Hence, the correct answer is option 2.
