The wounded man was carried by the King.
To change the sentence from active voice to passive voice, we need to rearrange the sentence structure and modify the verb form. In the active voice, the subject performs the action on the object. In this case, the subject is "the King" and the object is "the wounded man."
To convert it to passive voice, we make the object of the active sentence the subject of the passive sentence, and the subject of the active sentence becomes the object with the verb form changed.
In this case, "the wounded man" becomes the subject of the passive sentence, and "was carried" is the verb form used in the passive voice. The doer of the action (the King) is now mentioned using the preposition "by."
So, the passive voice sentence becomes "The wounded man was carried by the King."
