Choose the correct passive voice transformation of the sentence:
Someone has left the door open.
Show answer & explanation
Correct answer: A
Explanation
The original sentence, 'Someone has left the door open,' is in the present perfect tense. To transform it into the passive voice:
The object of the active sentence ('the door') becomes the subject of the passive sentence.
The verb tense must remain present perfect ('has been left').
The subject of the active sentence ('someone') is omitted as it is unspecified.
Therefore, the correct passive form is 'The door has been left open.'
