Choose the correct Passive Construction for the sentence given:

"Mrs. Sharma knows me."

The correct answer is 'I am known to Mrs. Sharma.'

Key Points  

• In the Active Voice, the emphasis is on the subject which performs an action.
• In the Passive Voice, the emphasis is on the object of the sentence which is the receiver or recipient of the action being performed. 
• In the given sentence, the subject is 'Mrs. Sharma' and the object is 'me'.
• The sentence is in the present indefinite tense.
• The structure is:
  • Sub + V1 (s/es) + object. 
• In the passive voice, the structure is:
  • Obj + is/am/are + the past particple (V3) + (by + subject).
• We use the preposition 'to' after 'known'. So, we won't use 'by' here.
• Therefore, the correct answer is option 3.
