Official Solution:


(1) \(y > x^2\). If \(x=1\) and \(y=4\), then the answer is NO but if \(x=y=\frac{1}{2}\), then the answer is YES. Not sufficient.

(2) \(y = x + 1\). The question becomes: is \(x \gt (x+1)^2\)? Which cannot be true for ANY value of \(x\). So, the answer to the question is NO. Sufficient.


Answer: B

The answer must be option B. My take :

Option A - Can be true or false depending upon the value of x and y. x and y could integers or fractions , hence the result will be inconsistent.

Option B - True. No value of x and y will satisfy this.

The answer must be B
