Don't you think the answer should be C?

nopes IMO E
whats your reasoning behind C?
I guess you thought of a right triangle. but the length of the third side will depend upon the angle between the two given sides

The powers of two are bloody impolite!!

Got it man!! I thought its a right angle triangle. 3 - 4 - 5. But it might be like this: 3 - 5 - X.

Yep definitely E. Had they stated that the triangle was right then C.

Because that condition was not given the values of YZ could be 2<YZ<8 when you combine both statements so C is not sufficient and E is the answer

Hello @umaa,

It would be nice if you can use Spoiler for OA's and IMO's.

Thanks,
