Question

Fill in the blank using the most appropriate option:

I'm afraid I can't come tomorrow. I _________ work late.

• A. has to
• B. had to
• C. have to
• D. has

Answer 1

The correct option is C have to

The option C is correct. The sentence is about future tense which speaks of the necessity or requirement. 'Have to' is the verb used for necessity or requirement. Thus 'Have to' option is correct. Option A and D are not feasible since they are used with present tense. 'Had to' is used with past tense.
