Answer»

Correct answer is (b) 4

Explanation: Since square roots cannot be NEGATIVE the OPTIONS stating -4 &-16 are ruled out. Now we are LEFT with two more options from which the 16 cannot be the answer as the square ROOT of any number cannot be that number itself . So the only answer left is 4. Hence 4 is the correct answer.
