Question

Fill in the blank with the most suitable option:
I ________________ very hard but I do now.

• A. Don't need to work
• B. Don't have to work
• C. Didn't have to work
• D. Should have worked

Answer 1

Answer: (C)

Didn't have to work

The correct solution is C. 'Have to' is used to refer necessity or requirement. The sentence speaks about the past tense. 'Did' is the helping verb of past tense with which base form of the verb is used. 'Work' is the base form of verb. Thus, options A, B and D are wrong.
