Answer:
B. had
Step-by-step explanation:
In the given sentence, the speaker expresses a desire for something they don't currently possess. The verb "wish" indicates a hypothetical or unreal situation. In English, when expressing a hypothetical wish for something that is contrary to reality, we use the past simple tense (simple past) in the "if" clause. In this case, the "if" clause is implied but not stated directly. The verb "had" is the past simple form of the verb "have" and is used to indicate a hypothetical or unreal situation. Therefore, the correct sentence is: "I wish I had a car, I'm tired of catching the bus."
To further illustrate, consider the following example: "I wish I had studied more for the test, I might have gotten a better grade." In this example, the speaker expresses a wish about something that didn't happen in the past (studying more), which could have resulted in a different outcome (getting a better grade).
In summary, when expressing a hypothetical or unreal wish about something contrary to reality, we use the past simple tense (simple past) in the "if" clause. Therefore, the correct answer is B. had.
