Do people that answer questions here at Y!A with a question do it because?

Some of A, B, C, D and E. This is why (for E): The person asks a question and it makes no sense at all, uses in-proper grammar etc. and the answerer does not understand the question so they ask them to ask it again, properly.

I think that all of the above apply to an assortment of those who answer. The other, well, for myself, i just enjoy reading and replying as well as the occasional interaction from an asker. At times, I have replied with a question, but only to help clarify what was asked; many questions are vague and at times the use of the English language is poor and difficult to comprehend as is as the spelling.

C) & some of D) They read the Community Guidlines but are forgetful.
