Answer :
B. When the source of information is relevant to only some parts of Franny's argument
The correct answer is C. When the source of information is written in a particularly brilliant or witty way
Explanation:
In writing, it is common the author uses in-text citation to strength his or her argument and develop appropriately the author's ideas for doing this the author can quote the source, which is about using the exact words used by another author; paraphrase that means using the ideas found on an external source but expressing them with your own words or summarizing the ideas of a source which means compiling multiple ideas of a source. The type of citation mainly depends on the purpose of the author and the type of content provided in each source.
In the case presented in which Franny is writing a research paper on "The Raven" by Poe, it is recommended Franny quotes the literary work "The Raven" as this is unique and uses multiple literary devices that would be lost if Franny paraphrases. But in the case of a secondary source which analyzes or summarizes "The Raven" Franny can paraphrase the content or quote it in case, the information is written in a particular way that would be lost if Franny paraphrases. Considering this, the statement that best describes when Franny should quote is "when the source of information is written in a particularly brilliant or witty way".
