Explanation:
Passive voice is often used to emphasize a verb or the object in a sentence. In active voice, emphasis is made on the subject i.ethe doer of the action but in passive voice, the verb or subject is emphasized.
Passive voice could also show that the subject in that case is either not too important or we don't know what or who the subject is.
A way to identify passive voice is to observe what happened and what the subject in the text is. If the subject i.e the doer is omitted or occurs after the action has taken place, it's a passive voice. Sometimes you can also identify it by looking at the verb. If it's in past participle, as in "had been" (used in option C), it's passive voice.
The presence of "by" (also present in option C), which also turns the position of object to subject is also an indicator of passive voice.
