The correct answer is: 14235.
The first word, “Jack”, is the subject of the sentence. The second word, “arrive”, is the verb. The third word, “next”, is an adverb that modifies the verb “arrive”. The fourth word, “week”, is the object of the preposition “next”. The fifth word, “will”, is the auxiliary verb.
The sentence can be paraphrased as follows: Jack will arrive next week.
Option A: 15234 is incorrect because the word “will” is not in the correct position. The auxiliary verb “will” should come before the subject “Jack”.
Option B: 14235 is the correct answer. The words are in the correct order.
Option C: 34251 is incorrect because the word “will” is not in the correct position. The auxiliary verb “will” should come before the subject “Jack”.
Option D: 14325 is incorrect because the word “will” is not in the correct position. The auxiliary verb “will” should come before the subject “Jack”.
