F(X) = sqrt(X) has + both positive and negative values of F(x) for all X >= 0. For example sqrt(4) has two values + 2 and -2. Option A is plotted for only positive values of sqrt(x). Option C is plotted for negative values of x for which f(x) is not defined. So Option B is the correct choice.

Actually, option A is the correct choice, since x \sqrt x can never be negative.
