Hi moneyman,
You're right - for choice A, you can plug in multiple values for X, and get the equation to work. However, if you tried this for choice B, you'll find that there are restrictions to what numbers can be used; you can only use 3 for X and 0 for Y, otherwise the conditions aren't satisfied. Remember, you can't plug in numbers that make the statement untrue. Thus, the correct answer to this question is B.
Hope this helps!

Thanks Jim..Got it!! I have my GMAT tomorrow..These questions are from the GMAT Prep I took yesterday on which I scored a 720..Surprising thing is that I got 17 wrong in the Quant section and still managed to get a 47..Is there something wrong with the software ?

It's hard to say - you can't evaluate your score based on the number you get right or wrong. Remember that harder questions count more, as do questions towards the beginning of the test. Still, I think 17 wrong leading to a 47 sounds a bit high, even if they were all difficult questions, but it's impossible to tell. Have you taken other practice tests? People tend to do roughly the same on the real test as they do on practice tests.
