Explanation:
y=1, x=1,then: 0=0
y=3, x=1,then: 123>4
y=1, x=3,then: -123<4

Explanation
Try plugging in values for x and y.
If x = 1 and y = 3, then Quantity A is \(2^7\) and Quantity B is \(2^2\).
Quantity A is greater, so eliminate choices (B) and (C).
Then try x = 1 and y = 1; now both quantities are equal, so eliminate choice (A) and select choice (D).
