Concept:Active voice places the doer (subject) before the action (verb). The passive voice has the receiver as the subject.
Rule / Clue:In the passive sentence, the agent after "by" becomes the active subject. The verb "have been being reviewed" (present perfect continuous passive) changes to "has been reviewing" (present perfect continuous active).
Explanation:The original sentence: "The documents have been being reviewed by the compliance team for several weeks."
The agent "the compliance team" becomes the subject. Use "has" (singular collective noun). The object becomes "the documents". The time phrase remains "for several weeks". Active form: "The compliance team has been reviewing the documents for several weeks."
Option A uses present perfect (not continuous) and shortens "several weeks". Option C stays passive with wrong tense. Option D changes tense and meaning (weekly duration). Only Option B matches the correct active continuous tense.
Answer:Option B: The compliance team has been reviewing the documents for several weeks.
