Choose the suitable option that expresses the given Active Voice sentence in the Passive Voice.

'Who knows you?'

To whom are you known?

The suitable option that expresses the Active Voice sentence "Who knows you?" in the Passive Voice is: To whom are you known?

Here's why:

• Converting to Passive Voice: To transform an Active Voice sentence to Passive Voice, we need to swap the subject and object, and add the auxiliary verb "be" in the appropriate tense.
• Original Sentence: In "Who knows you?", the subject is "who" and the object is "you."
• Passive Voice Transformation: Therefore, in Passive Voice, "you" becomes the subject and "who" becomes the agent introduced by the preposition "by." However, in English, we often replace "by" with "to" before a person in passive sentences. Since the tense of the original sentence is present, we use the present tense of "be" ("are").
• Correct Option: Hence, the correct Passive Voice form is "To whom are you known?"
