Question

Fill in the blank with a suitable option:
If my car __________ start, I will be late.

• A. didn't
• B. doesn't
• C. don't
• D. did

Answer 1

The correct option is B doesn't

The given sentence is a Type 1 conditional, because it presents a possible condition (if-clause) and its probable result.

In such sentences, the if-clause is in simple present tense and the main clause is in the simple future tense ('I will be late').

Option B: 'Doesn't' is in the simple present tense. It completes the sentence in meaning as well as agrees with the Type 1 structure. Hence option B is correct.

Option A: 'Didn't' is in the past tense. It isn't used in the first conditional.

Options C and D: Similarly, 'did' refers to the past tense. 'Don't' is used when speaking in the first and second plural and singular, while 'doesn't' is used for third person singular 'car'.

Hence options A, C and D are incorrect.
