• B. He had to smoke.

• D. He has to smoke.

Answer 1

Answer: (C)

He didn't use to smoke.

The correct option is C. 'Didn't use to' means something that happened but doesn't happen any more. It shows past tense. It always means something that happened in the past, it should always use past tense. Options B and D are incorrect as they denote necessity or requirement. Option A is wrong as 'use to' is used. Thus option C is right.
