Answer: C.
Explanation:
question is "Based on the excerpt, what causes Cassie to almost lose her temper?
Stacey telling everyone that they will not say anything
T.J. talking to everyone about all of his worries
Stacey saying that Cassie’s business is her business
T.J. accusing Cassie of Uncle Tomming Lillian Jean"
None or a thing, or an adverb clause
The correct answer is B, because "who all students love" should definitely follow Mr. Rapture, and not "chemistry lab" like in A, and there should be a comma because this is an appositive.
