The correct answer is A. 25431.
The first option, “any”, is the subject of the question. The second option, “is”, is the verb. The third option, “his”, is the possessive pronoun. The fourth option, “better”, is the adjective. The fifth option, “friend”, is the object of the preposition “of”.
The other options are incorrect because they do not follow the rules of English grammar. For example, option B, “23514”, does not have a subject. Option C, “25413”, does not have a verb. Option D, “54231”, does not have an object.
I hope this explanation is helpful. Please let me know if you have any other questions.
