C - sat in the back
They didn’t ask for the sentence right?
If they didn’t ask, then it’s still C.
Exception means to take out or exclude. In a sentence: Everyone must do the homework with the exception of Nick since he was out yesterday. It means that he is excluded from doing the work. I hope this helps/makes sense lol!
If your talking about which one does not make sense then its the because its supposed to be "The"... i don't get your problem
