Question

Fill in the blank with the most appropriate word.
They would buy the car if they ________ enough money.

• A. would have
• B. had
• C. have had
• D. had had

Answer 1

The correct option is B had

Option A is incorrect as 'would have' is used to talk about something you wanted to do but didn't.
Option B is correct as the verb 'have/had' (had is the past participle) indicates possession. Here, it fits as it indicates that they would have bought the car if they has possession of enough money.
Option C is incorrect as 'have had' is used indicate being so annoyed with someone or something that you do not want to be involved with them any longer.
Option D is incorrect as 'had had' is the form of past perfect tense of the verb 'to have'. It is quite often used in the reported speech.
Thus, option B is correct.
