Pardon me

You are right, 0 does not satisfy. It is either -1 or 1 for statement A.

Still the answer is D. In neither case, the number is not a prime. Is that right?.

Is X a prime number?

(1) |X|=1^X

(2) X=1^|X|


1 is sufficient to answer: NO.

2 is also sufficient to answer: NO.

Both are sufficient...
