Final answer:
Without additional context such as the book title or author, an accurate answer to which friend named Trevor always got into trouble with is not possible. Trevor's friend could be Sizwe if the book is 'Born a Crime' by Trevor Noah.
Step-by-step explanation:
The question seems to be about a character named Trevor from a book or narrative, and his friends during middle school. Without additional context, such as the title of the book or the author's name, it is impossible to provide an accurate answer to which friend Trevor always got in trouble with.
If the book in question was 'Born a Crime' by Trevor Noah, then the answer would be b) Sizwe, as Trevor details various mischievous adventures with Sizwe during his school years. However, since the exact source material is not specified, I cannot confidently confirm this answer.
