Subject-verb agreement problem

C

First of all, the subject and predicate agree. Nobody is the subject and uses a singular predicate, which has nothing to do with the noun after except

The answer should be C/D

Then there is the meaning, been to/gone to. The difference is that the former has been and has come back, while the latter has been and has not returned yet

In terms of meaning, it is judged that it should be back, let’s talk about experience.

So choose C
