Its a Tricky one . I have selected option C . .

Look at the question carefully.
OPtion B:

x^2=4;
x=+/-2;
|x|=2;
whatever you take ! -2 or +2 the mod value is always positive.!!

Yes.

From (1) we have that $$x\leq{0}$$ and from (2) we have that x = 2 or -2. So, when combining we can get that x = -2.
