Question

Choose the correct passive of the given sentence : 
Did he kill a lion ?

Accepted Answer

Option 3, "Was a lion killed by him?" is the correct passive voice transformation of the active voice sentence "Did he kill a lion?". Here's why:

*   **Why Option 3 is Correct:** The original sentence is in the simple past tense (interrogative form). To convert it to passive voice, we need to use the past tense form of the auxiliary verb "be" (was/were) followed by the past participle of the main verb "kill" (killed). Since "a lion" is singular, we use "was." The subject "he" in the active voice becomes the object "him" in the passive voice, preceded by "by." Therefore, "Was a lion killed by him?" correctly reflects the passive voice transformation.

*   **Why Option 1 is Incorrect:** "Did a lion killed by him?" is grammatically incorrect. The auxiliary verb "did" is used in the active voice, not the passive voice. Also, "killed" should be preceded by a form of "be" in the passive voice.

*   **Why Option 2 is Incorrect:** "Was a lion killed by you?" changes the meaning of the sentence. The original sentence asks about "he," not "you." The passive voice transformation must maintain the original subject's reference.

*   **Why Option 4 is Incorrect:** "Had a lion been killed by you?" uses the past perfect tense ("had been killed"), which is not the correct tense to transform the original simple past tense sentence. Also, like Option 2, it incorrectly uses "you" instead of "him," changing the meaning.
