Imagine person A and person B are talking to each other.A tells B about what person C said to A. A uses the same sentences what C said but A could not understand what C meant exactly.Now B knows what C said to A. B have some idea or guess what C meant but B is not sure either.So B makes some guesses based on what C said.
I'd like to ask how B should start his sentence when he makes guess about what C meant?
B says to A:
1.C could mean...
2.C could have meant...
3.C may/might mean...
4.C may/might have meant...
5.C would have meant...
