I have read a question in a test and I am very confused about the answer.
They must have come to school, ______?
A. mustn't they B. shouldn't they C. didn't they D. haven't they
I think that A will be the correct answer but the answer in the key is C.
Would you please give me the best choice? Thanks a lot
