The correct answer is: B. Cakes are made by her every Sunday.
The sentence “She makes cakes every Sunday” 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 “makes.” 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 “Cakes are made by her every Sunday.”
The other options are incorrect because they are not in the passive voice. Option A, “Every Sunday cakes made by her,” is in the active voice. Option C, “Cakes make her every Sunday,” is in the active voice and the subject and verb are reversed. Option D, “Cakes were made by her every Sunday,” is in the past tense.
Here is a diagram that shows the difference between the active and passive voice:
Active voice:
Subject + verb + object
She makes cakes.
Passive voice:
Subject + verb + be + past participle
Cakes are made by her.
I hope this helps!
