---I can't find my keys anywhere. I saw them on the table this morning.
---I think you ________ them in your car.
A. may have left B. could have left
Which one is acceptable for the situation above? And what is the difference between the two? I always can't tell! Thanks for help.
Both "may have + past participle" and "could have + past participle" are used to express the possibility in the past.
For this reason, A and B are both acceptable, in my opinion.
