Fill in the blank with a suitable modal:
A: I've got toothache.
B: You'd _________ go to the dentist.

• A. Better
• B. Should
• C. Used to
• D. Must

Answer 1

The correct option is A Better

The correct answer is Option A.

BETTER is used to express a desirable action.

In the given sentence, B is telling A that it is desirable that he goes to the dentist.

Thus BETTER is the correct answer.

The remaining options are incorrect because:

SHOULD expresses obligation or duty.

USED TO refers to the past tense.

MUST expresses compulsion.
