ans is A.
exp:
1. lets take a few examples it says X^2>y^2 so
3^2>2^2
6^2>5^2
6^2!>(-7)^2 (not greater than)
with all these examples we can def say A is sufficient.
2. x>y
3>2
-2>-3 --> |-2| is not greater than |-3| with equation 2 we cannot say if |x| > |Y|.
Hence the ans A. Please let me know if this helped. Also do reply back is this answer is wrong.
