Select the option that expresses the given sentence in active voice.
He must be written to by us.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. We must write to him.
The original sentence “He must be written to by us” is in passive voice with a modal verb “must.”
To change it to active voice, the subject “we” must perform the action directly, keeping the modal verb “must.”
Option 4 correctly expresses this in active voice: “We must write to him.”
Option 1 is present continuous, not matching the modal “must.”
Option 2 is present perfect continuous, unrelated.
Option 3 is incomplete and doesn’t match the modal verb “must.”
