Best answer
Correct answer is (d) false

Best explanation: For an empty string (“”), the Boolean value is false. E.g. var t= “ ”; Boolean(t); //it will return false. For -0(minus zero), the Boolean value is false. The Boolean value of undefined is also false. For null and false the Boolean value is also false.
