Select the option that expresses the following sentence in passive voice.
He had cleaned the bathroom.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. The bathroom had been cleaned by him.
The sentence "He had cleaned the bathroom" is in the active voice, where the subject "He" performs the action. In passive voice, the focus shifts to the object "the bathroom," which receives the action.
To form the passive voice, the object becomes the subject, and the verb tense remains consistent by adding the appropriate form of "to be."
Thus, the past perfect tense "had cleaned" becomes "had been cleaned." Adding "by him" clarifies the doer of the action, resulting in "The bathroom had been cleaned by him."
