C it's doing something

To answer this question correctly, you need to know what passive voice is. Passive voice basically occurs when you make the object of an action into the subject of a sentence. So in this case, the answer to your question would be c)I tossed the newspaper gently into the backyard because the reader's attention first goes to you tossing the newspaper, but when the reader finishes reading the statement their attention goes to the newspaper.

It’s the first one.
