The correct answer is: B. Her day is begun with a cup of coffee.
The sentence “She begins her day with a cup of coffee” 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 “begins.” The object of the sentence is “her day.”
The passive voice is formed by using a form of the verb “to be” followed by the past participle of the main verb. In this case, the passive voice sentence would be “Her day is begun with a cup of coffee.” In the passive voice, the subject of the sentence receives the action. In this case, the subject is “her day” and the action is “begun.”
The other options are incorrect because they are not in the passive voice. Option A, “Her day is being begun with a cup of coffee,” is in the progressive passive voice. The progressive passive voice is formed by using a form of the verb “to be” followed by the present participle of the main verb. In this case, the progressive passive voice sentence would be “Her day is being begun with a cup of coffee.” In the progressive passive voice, the subject of the sentence is still receiving the action, but the action is happening over time.
Option C, “A cup of coffee is beginning her day,” is in the active voice. Option D, “A cup of coffee has begun her day,” is in the perfect passive voice. The perfect passive voice is formed by using a form of the verb “to have” followed by the past participle of the main verb. In this case, the perfect passive voice sentence would be “A cup of coffee has begun her day.” In the perfect passive voice, the subject of the sentence has already received the action.
