Dear All,

I encountered the following question while attempting a practice test in

The answer given was: Choices B and C are the correct answers.

Is this correct?
Of course C is correct; but if B is correct the case when x == y will make z = x; where as in the given code z = y for the same case right?
I thought the question was an easy one; but now confused Please help!

taking option b
the end result is still the same
whether z=x or z=y, both the answers will be the same,right?

myself got confused in this one at first...

when x==y, does it matter what it returns??? Because x and y are the same!!!..
