i would say that you do not have to worry about this kind of situation.
The real exam does not come with weird or ambiguous questions like this one.
At least i hope !

[Anitha Srinivasan]

Yes. It shouldn't be.
I just want to know anyone had experience like this.

Thanks,
Anitha

I think, context of the question is "From where log(..) methods come from?" So, the answer is A,D.

Because, origin of log(..) is from GenericServlet class and ServletContext interface.
