The correct answer is A. 51234.
The first word is “I”, which is a pronoun that refers to the speaker. The second word is “have”, which is a verb that means to possess something. The third word is “my”, which is a possessive pronoun that refers to the speaker. The fourth word is “car”, which is a noun that refers to a vehicle. The fifth word is “own”, which is a verb that means to possess something.
The sentence “I have my car” means that the speaker possesses a car. The sentence can be rearranged in different ways, but the meaning will remain the same. For example, the sentence can be rearranged as “My car I have” or “Have I my car”.
The other options are incorrect because they do not make sense in the context of the sentence. For example, the sentence “Car my have I” does not make sense because the word “car” comes before the word “my”. The sentence “Own I my car” does not make sense because the word “own” comes before the word “my”. The sentence “Car I own my” does not make sense because the word “car” comes after the word “own”. The sentence “Own my car I” does not make sense because the word “own” comes after the word “car”.
