Answer:
B. The Writer's thesis and interpretation.
Step-by-step explanation:
An endnote is a reference, comment or explanation of certain words or quotes used in the essay, work or research paper at the end of the article or work to provide additional information about the topic in the context of the work. They are employed with two purposes where the acknowledgment of the source is the first while the another is to provide explanatory comments about unfamiliar words to help the audience relate its meaning. Thus, it must compliment the writer's thesis an interpretation as if the comments or reference negate or contradict the author's thesis, the consequences would be undesired.
