Answer: <span>A. The hungry housecat killed the small, grey mouse last Tuesday and left it on the doorstep.</span>
<span>With active voice the subject, in this case the housecat is doing the action. So with this sentence, the cat killed the mouse and then left it on the doorstep.</span>
<span>Passive voice sentences usually use the word was like in three of the four examples you gave. </span>
<span>In example B the following wording was used: was left, was killed (that is passive voice).</span>
<span>Example C: was left</span>
<span>Example D: was killed</span>
<span>While example C and D start off using active voice (the hungry housecat killed) it finishes using passive voice. The tenses should remain the same throughout the sentence. </span>
<span>Hopefully this helped and good luck</span>

My best guess is B. The others look questionable
