To determine the correct answer in this case, you need to consider the verb tense consistency. The pronoun "he" is referring to a person in the past, so the verb tense used should also be in the past tense. Out of the given options, option B is the only one with the correct past tense verb form, "arrived." Therefore, option B is the correct choice.
