I _______ go to the dentist. I've had toothache for 3 days.
(A) must
(B) have to
(C) must to
(D) has to
I think choice (B) is correct because the speaker actually doesn't want to go to the dentist but his/her toothache forces him/her to do so. Am I right? Thank you.
I would use ( B). But some native speakers would use ( A).
