Which of the following options is the most suitable conversion of the following sentence into active voice?
Had the final draft of the proposal been prepared by the secretary before the deadline?
Show answer & explanation
Correct answer: C
Explanation
The original sentence "Had the final draft of the proposal been prepared by the secretary before the deadline?" is in the past perfect passive voice. To convert it to the active voice, the subject (the secretary) must perform the action (prepared). The tense must remain the same (past perfect).
The passive voice structure is: Had + object + been + past participle + by + subject + ?
The active voice structure for an interrogative sentence in the past perfect tense is: Had + subject + past participle + object + ?
Option (C) correctly follows this structure and maintains the original tense and meaning.
