Data Sufficiency

Solution:
The question is asking whether x.lyl > y2 or not.
Now y2 = lyl.lyl.
Or we need to know whether x.lyl > lyl.lyl or not?
Since lyl > 0, we divide both sides of the above inequality by lyl without changing the inequality sign.
Or we can say, we need to know whether x > lyl or not.
Let us consider first (1) alone.
It says x > y.
Now, let x = 2 and y = -3. Or lyl = 3.
Here, since 2 > -3, x > y but x < lyl.
Next, let x = 4 and y = 3. Or lyl = 3.
Here, since 4 > 3, x > y and x > lyl.
So, from (1) alone, nothing definite can be said.
Next, let us consider (2) alone.
It says y > 0.
But, we know nothing about x.
Or (2) alone is not sufficient to answer the question.
We next combine both the statements together and check.
On combining, we have that x > y and y > 0.
If y > 0, lyl = y.
Or x > lyl.
So, the answer to the main question is yes.
Or both statements together are sufficient to answer the question.

The correct answer is (C).
