Choose the suitable option that expresses the given Active Voice sentence in the Passive Voice.
'Who knows you?'
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → To whom are you known?
Passive of a question beginning with "Who":
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | you (object) | you (subject) | The object “you” becomes the subject. |
| Tense kept | knows | are ... known | Simple present “knows” becomes are known (“are” agrees with “you”), placed before the subject because it is a question. |
| Agent (by ...) | Who | To whom | The question word Who becomes By whom. With “know” the usual preposition is to (known to someone), so the sentence is “To whom are you known?” |
| Full sentence | Who knows you? | To whom are you known? |
Example: Who knows the answer? → To whom is the answer known?
Why the Other Options are Incorrect?
Option 2: To whom were you known? — Incorrect. "Were" is the past tense. "Knows" is present.
Option 3: To whom was he known? — Incorrect.
- It changes the person from "you" to "he".
- It changes the tense to the past.
Option 4: To whom is he known? — Incorrect. The tense is right, but the subject should be "you", not "he".
