The correct answer is A. It is the name of her sister.
Explanation:
In "Everyday Use" by the American writer Alice Walker the narrator is an Afro-American woman (Mama) who has two daughters: Maggie and Dee. During the story, as Dee is visiting her mother and sister she claims she does not want to be called "Dee" but instead she wants to be called "Wangero Leewanika Kemanjo" as she believes "Dee" is a name inherited from previous slavers and her new name with an African origin is more appropriate; however, her mother explains to her, she was named after her aunt Dee and thus, the name Dee is important to the narrator because this was the name of her sister and the reason she called in that way one of her daughters.
