The correct answer is: C. Her husband was taunted by her with the memory of his early promise.
The sentence “She taunted her husband with the memory of his early promise” is in the active voice. In the active voice, the subject of the sentence performs the action. In this case, the subject is “she” and the action is “taunted.” The direct object of the sentence is “her husband” and the indirect object is “the memory of his early promise.”
The passive voice is formed by using the verb “to be” and the past participle of the main verb. In this case, the passive voice sentence would be “Her husband was taunted by her with the memory of his early promise.” In the passive voice, the subject receives the action. In this case, the subject is “her husband” and the action is “taunted.” The direct object of the sentence is “the memory of his early promise” and the agent of the action is “she.”
The passive voice is often used when the identity of the agent is not important or when the focus is on the action itself. In this case, the identity of the agent is not important, so the passive voice is a good choice.
The other options are incorrect because they are in the active voice. In the active voice, the subject performs the action. In these cases, the subjects are “her husband” and “the husband.” However, the subjects do not perform the action of “taunt.” The action is performed by “she.” Therefore, the active voice is not a good choice for these sentences.
