The sentence describes an event happening in the future, indicated by the phrase "By the time the guests arrive." However, the verb in part (B), "prepared," is in the past tense. This creates a tense disagreement with the rest of the sentence. To correct the error, we need to change the verb in part (B) to the present perfect tense. The present perfect tense is used to describe actions that happened in the past but have a result or relevance to the present.
