Correct Answer: A great lesson was learnt by me from my failure.

Solution : The correct choice is the second option .

Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active voice becomes the subject in the passive voice.

The structure of the passive voice in the case of the simple past tense is: "Singular object + was + past participle form of the main verb + 'by' followed by the agent of the action + prepositional phrase."

Therefore, the sentence in passive voice is: A great lesson was learnt by me from my failure.
