Convert to passive: The boy kicked the ball.

## The reasoning To convert active to passive voice, follow this formula: **Object becomes subject + appropriate form of "be" + past participle + "by" + original subject**. Here's the transformation: - **Active**: The boy (subject) kicked (past tense verb) the ball (object). - **Passive**: The ball (new subject) + was (past tense of "be") + kicked (past participle) + by the boy. Since "kicked" is past tense, we use **"was"** (not "is"). The action already happened, so the passive must also be in past tense. ## Why the wrong options tempt you **B** uses "is kicked" — this makes it present tense, but the original sentence is past tense. The timing doesn't match! **C** just swaps the subject and object without changing the verb structure. Now the ball is doing the kicking — completely wrong meaning. **D** says "be kicked" — grammatically broken. You can't use bare "be" without a helping verb like "will" or "should." ## Quick takeaway **Match the tenses!** If the active sentence is past, your passive "be" verb must be past too (was/were), then add the past participle.
