When a critic is attempting to interpret a piece of writing, the question that he must ask is "How did the author say it?". The correct answer is C.

Explanation:

When writing, an author can speak about many usual or unusual subjects; for example: love. Love is a very common subject, but the greatness about an author and his/her work is not in the subjects he/she chooses, but in the way he/she writes about it, what he/she does with the subject. We -readers- can even disagree with the author's beliefs about the subject, that is why it doesn't really matter what he/she says about it. What it really matters is the unique way in which the author expresses him/herself in the piece of work.

he can eat everything and drink whatever he wants
