What one can try is to look for other options which will satisfy D, for different test cases. But i doubt that will happen, under the stipulated time limit of trying to solve a question in 23 minutes. Let me know if this helps you in anyway Posted from my mobile device

Take X=100 Y=1 how can D be the Answer?

It should be 0.5>1 after reciprocal which is a yes. Also in D, it can be proven wrong if we take 5 & 5

None of the options is correct. All give Yes or No as answers.
