Final answer:
Option B (2 car/drives) is correct because 'car' is a singular subject that agrees with the singular verb 'drives'. Subject-verb agreement is essential and can be complex in some sentences.
Step-by-step explanation:
To determine which subject and verb are in agreement, one must ensure that singular subjects have singular verbs and plural subjects have plural verbs. Among the options provided, option B is correct because the subject 'car' is singular and 'drives' is the corresponding singular verb.
Subject-verb agreement is crucial in crafting grammatically correct sentences. Compound subjects joined by 'and' usually take a plural verb. However, when they form a single unit, the verb is singular. When the compound subjects are joined by 'or' or 'nor,' the verb should agree with the subject that is closest to it. It's also important to maintain agreement when other words come between the subject and the verb or when the verb comes before the subject.
As for the use of indefinite pronouns, most take a singular verb. Always remember that subject-verb agreement may get complex in certain sentences, and in these cases, one should carefully check to ensure correct agreement.
