Answer:C.Setting up a rejection of two options.
Explanation:"Neither" and "nor" are conjunctions that are used to link two negative statements together, setting up a rejection of two options. In this sentence, "Neither Yolanda nor Rosianna likes anchovies" means that both Yolanda and Rosianna dislike anchovies, and it's a way of expressing the negative of both subjects. It is a negative form of "either...or" statement.
