Convert to passive: 'The boy kicked the ball.'

**The reasoning** In passive voice transformation, the **object becomes the subject** and the original subject becomes the "doer" (introduced by "by"). The verb changes to: **be + past participle**. Here's the formula: - Active: Subject + Verb + Object → **The boy kicked the ball** - Passive: Object + was/were + past participle + by + Subject → **The ball was kicked by the boy** Since "kicked" is past tense, we use "was" (past tense of "be") + "kicked" (past participle). The ball (originally the object) is now the subject receiving the action. **Why the wrong options tempt you** - **B** uses "is kicked" — that's present tense, but the original action happened in the past (kicked, not kicks) - **C** reverses roles incorrectly — now the ball is doing the kicking! That completely changes the meaning - **D** "be kicked" has no proper tense — "be" alone can't work as a main verb; it needs "was/is/will be" **Quick takeaway** To convert active to passive: flip the object to subject position, match your tense with "be," add the past participle, then "by" + original subject. Always keep the same tense!
