From the given alternatives, choose the one which best expresses the sentence in Active/Passive voice.
Do you imitate them?

Are they imitated by you?

The correct answer is Are they imitated by you?

The original sentence is in active voice, with the subject "you" and the verb "imitate". To change it to passive voice, we make the object of the active sentence, "them", the subject of the passive sentence. The verb "imitate" becomes "are imitated", and we add the preposition "by" to show who is doing the action. This gives us the passive voice sentence "Are they imitated by you?".

The other options are incorrect.

• Do you imitate them? is in active voice, and it is the original sentence.
• Have they being imitated by you? is in the present perfect passive voice. This sentence is not appropriate for the original sentence, which asks a question about the present.
• Were they being imitated by you? is in the past progressive passive voice. This sentence is not appropriate for the original sentence, which asks a question about the present.
