Explanation
Try Plugging In; one set of values that could work is x = −2, y = 0, and z = 2.
In this case, both Quantity A and Quantity B have a value of 0. Eliminate choices A and B.
However, another set of values that could work is x = −6, y = −4, and z = −2.
With this set of values, Quantity A has a value of 24 and Quantity B has a value of 8. Eliminate choice C. You are left with choice D for the answer.

D)The relationship cannot be determined from the information given.
Let's test some values.
Try x = -2, y = 0 and z = 2 (NOTE: 0 is even, so these ARE consecutive even integers)
Quantity A: xy = (-2)(0) = 0
Quantity B: yz = (0)(2) = 0
The Quantities are equal
Try x = 0, y = 2 and z = 4
Quantity A: xy = (0)(2) = 0
Quantity B: yz = (2)(4) = 8
Quantity B is greater
