IMo E

1. y!=6 and x! > 720

Insufficient , we dont know anything about Z and X could take multiple values.

2. z is the least even integer greater than -1

Least even integer greater than -1 is 2

Zero is positive in GMAT world( Please correct me if I am wrong)

Combining we dont have a definite value for X

SO E

Zero is neither positive nor negative. zero is definately even everywhere. So I think answer is B

I agree: 0 is neither positive, nor negative, but is even.
So, statement II tells us that the expression xyz=0

B
