Change the following sentence into the Active form.
The door has been locked.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: Someone has locked the door.
Explanation
• The given sentence is in the passive voice and uses the Present Perfect Tense (has been + V3).
• When the agent (doer) is omitted in passive voice, an indefinite pronoun like Someone is used as the subject in active voice.
• The structure for active voice in present perfect tense is: Subject + has/have + V3 + Object.
• Applying this rule: Someone (singular subject) + has + locked (V3) + the door (object).
