A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Lets take y = 4
So Quantity A = 2^4 = 2*2*2*2 = 16
Quantity B = (1/2) ^ - 4 = with the help of negative exponent rule this becomes, 2 ^ 4 = 2*2*2*2 = 16
Quantity A = Quantity B
So the answer is both quantity are equal i.e. C
