This is NOT a GRE question. Moreover is badly written

We do know that x is different from zero. Therefore, it could be any number, 1 included

BUT if x=1

quantity B is undefined because in the denominator 1-1 is ZERO

\(\frac{1}{0}\) is impossible or undefined.

I have a heartful suggestion to you sir: you have here on the forum over 12k quant questions and 90% of them are GOOD GRE questions.

I do not believe you need to find such bad questions where else.

Humble opinion

This is an easy question

a=1

then QA is 2 and QB is 0

a=-4


Then QA is -3 and B is -5/4

D is the answer
