Target question: Is xy > 6 ?
Statement 1: 2 ≤ x ≤ 4 , 3 < y < 5
The LEAST possible value of x is 2.
If it were possible for y to equal 3, then xy = (2)(3) = 6
However, it is NOT possible for y to equal 3, since the statement tells us that y is GREATER THAN 3.
So, the least possible value of xy must be greater than 6.
So, we can be certain that xy > 6
Since we can answer the target question with certainty, statement 1 is SUFFICIENT
Statement 2: x – y = 0
There are several values of x and y that satisfy statement 2. Here are two:
Case a: x = 3 and y = 3, in which case xy = (3)(3) = 9. In this case, xy IS greater than 6
Case b: x = 1 and y = 1, in which case xy = (1)(1) = 1. In this case, xy is NOT greater than 6
Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT
Answer: A
Cheers,
Brent

To me answer A makes the most sense.
I also assumed that GMATPrepNow meant A, not be. Correct me if I am wrong
