Correct Answer: The lottery will be won by Rakesh.

Solution : The third option is the correct answer.

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 sentence becomes the subject in the passive voice.

The structure of the active sentence in the case of the simple future tense is: "Subject + will + be + past participle form of the main verb + prepositional phrase."

Therefore, the correct answer is: "The lottery will be won by Rakesh."
