B. In a standard public classroom (Apex)
Our homework is corrected by the teacher
Although the teacher is doing the action, the subject of the sentence is "our homework". It also uses a form of to be (in this case it is "is"). Both of these things are what makes a passive sentence.
Hope this helped!
To show emphasis, the helping verb that would be used to fill the blank in the sentence would be do. I do think I have mastered french pronunciation. Hope this helped :D
