Which of the following options is the most suitable conversion of the following sentence into active voice?
Several key policies have been introduced by the government to promote renewable energy.
Show answer & explanation
Correct answer: A
Explanation
The original sentence, "Several key policies have been introduced by the government...", uses the present perfect passive voice ("have been introduced"). To convert it to active voice, the subject (the government) must perform the action (introduced) in the same tense (present perfect active: "has introduced"). Option A correctly maintains the original tense and meaning by making "The government" the subject of the active verb "has introduced".
