Answer: A) She was chosen by the committee to lead the parade.
Explanation: A sentence is in a passive form when the subject of the sentence doesn't perform the action of the verb, instead the subject receives the action (because it is also the direct object of the sentence). A verb in passive form has the structure of verb "to be" in present or past, plus a verb in participle. From the given sentences the one that has a passive verb is option A, the verb is "was chosen" and we can see that even if "she" is the subject, the action is performed by "the committee."
