Here's a question:
--May I put my bike here?
--No, you ________.
A. may not B. can't C. might not D. mayn't
The key is B.
Do we have to answer like that when meeting such kind of question?
I wonder whether other three are O.K. too.
Cause in my opinon, moder verb like may and can sometimes differs in possibility.
Is the sentence correct in grammar if other three are chosen?
