Which of the following options is the most suitable conversion of the following sentence into Passive Voice?
Doesn't the security guard lock all the museum doors?
Show answer & explanation
Correct answer: D
Explanation
The original sentence "Doesn't the security guard lock all the museum doors?" is in the simple present tense and is an interrogative sentence (a question). To convert it to the passive voice, the tense and the interrogative structure must be maintained. The object of the active sentence ("all the museum doors") becomes the subject of the passive sentence. Since "all the museum doors" is plural, the auxiliary verb "are" is used. The correct structure for a negative interrogative in the simple present passive is "Aren't + subject + past participle + by agent?"
Option (D) correctly follows this structure.
