EnglishVoice, Narration & Sentence Transformation
What is the most appropriate passive form of "Who has done the work?"
- a.Who has been done the work?
- b.By whom has been done the work?
- c.Whom has done the work by?
- d.By whom has the work been done?
Answer: (D) By whom has the work been done?
In the passive voice, the object of the active sentence becomes the subject, and 'by whom' replaces 'who'. The correct passive is 'By whom has the work been done?' — note 'has been done' (present perfect passive) with the auxiliary correctly placed.
