Fill in the blank with the most appropriate word. I’ll wait until he ________.

arrives
will arrive
is arriving
arrived

The correct answer is: A. arrives

The verb “arrive” means to come to a place after a journey. In this sentence, the speaker is saying that they will wait until the person they are talking about arrives at a certain place. The other options are not correct because they do not express the idea of waiting for someone to arrive.

  • Option B, “will arrive,” is in the future tense. This would be correct if the speaker was saying that they will wait until the person arrives at a certain time in the future. However, the sentence does not specify a time, so the future tense is not necessary.
  • Option C, “is arriving,” is in the present progressive tense. This would be correct if the speaker was saying that they are currently waiting for the person to arrive. However, the sentence does not specify that the speaker is currently waiting, so the present progressive tense is not necessary.
  • Option D, “arrived,” is in the past tense. This would be correct if the speaker was saying that they waited until the person arrived at a certain time in the past. However, the sentence does not specify a time in the past, so the past tense is not necessary.

Therefore, the correct answer is A, “arrives.”
