The correct answer is A. 2413.
The first option, 2413, is the only option that places the word “someone” first. This is because the word “someone” is the subject of the sentence, and the subject always comes first in a sentence.
The second option, 4312, places the word “powerful” first. However, the word “powerful” is an adjective, and adjectives usually come after the noun they modify. In this case, the noun is “someone,” so the adjective “powerful” should come after “someone.”
The third option, 4321, places the word “is” first. However, the word “is” is a verb, and verbs usually come after the subject of the sentence. In this case, the subject is “someone,” so the verb “is” should come after “someone.”
The fourth option, 3412, places the word “he” first. However, the word “he” is a pronoun, and pronouns usually come after the noun they refer to. In this case, the noun is “someone,” so the pronoun “he” should come after “someone.”
Therefore, the correct answer is A. 2413.
