I don't understand... why couldn't it be A?

1) Sufficient?
2^2 = 4.
-2^-2 = 1/2*1/2 = 1/4.

2) Insufficient. It could be 2 or -2.

I thin it's $$|n|^{|n|}=4$$

Find an integer N.

(1) $$|n|^{|n|}=4$$ --> $$n=2$$ or $$n=-2$$. Not sufficient.

(2) $$n^4=16$$ --> $$n=2$$ or $$n=-2$$. Not sufficient.

(1)+(2) Still the same two values of $$n$$ are possible. Not sufficient.
