St1:
Insufficient. Could be -1^2 or 1^(anything).

St2:
Insufficient. Could be z^0.

Using St1 and St2:
We know z = 1. Sufficient.

Ans C

1. n is a nonzero integer
2. z>0

1) n is non zero so the only way z ^n = 1 is if Z = 1 suff

2) z>0 which means n = 0 for z^n= 1 so Z can be anything insuff

I think it is A OA please

Answer is C


reason why it cannot be A is because

z can be 1 or -1 when n=2! (satistfies given eq and option 1)!
