Since the exponent/ power of x is even, the unique value of x cannot be determined. (As both positive and negative value of x gives same value of \(x^2\)) Hence Answer shall be E

Hi
I encountered a similiar type of question on the gmat club tests but I cannot locate it. I have a doubt on this question. IMO the answer should be E.
Statement 1: If y=2 X may be 5 or -5 Hence xy may be 10/ -10.
Statment 2: y=2 then x may be 5/-5. so xy may be 10/-10
Hence the answer should be E. Am I correct in my reasoning?
