I loved this book lol anyway the problem in the book was all the people/ characters in the book who were "evil" and how they solved it was trying to become it's friend or fighting and defeating it. The two main characters were Jesse and Leslie who were best friends. They both have big imaginations and decided to build a secret land together.
The answer is c. Theo, is there a bug on my back?
This is because for the other three sentences, the commas do not agree with the places they were put in. If you read the sentences aloud, you can hear that it sounds awkward.
