Change the active voice to passive voice : I have done my work .

The correct answer is '2' i.e. My work has been done by me.

Key Points

• The given sentence is in the active voice, where the subject (I) performs the action (have done) on the object (my work).
• When changing a sentence from the active voice to the passive voice:
  • The object of the active voice sentence (my work) becomes the subject of the passive voice sentence.
  • The verb changes to its passive form, which is has/have + been + past participle.
  • The subject of the active voice sentence (I) becomes the agent introduced by "by" (by me).
• Thus, "I have done my work" in the passive voice becomes "My work has been done by me."

Correct sentence: My work has been done by me.

Additional Information

• Active Voice: The subject performs the action.
  • Example: She is writing a letter.
• Passive Voice: The subject receives the action.
  • Example: A letter is being written by her.
• Key Rule: Only transitive verbs (verbs with an object) can be changed into the passive voice.
