Answer:
B. Joseph Asagai.
Step-by-step explanation:
The novel "A Raisin in the Sun" by Lorraine Hansberry revolves around an African-American family and their struggle to be accepted in American society. The novel deals with themes of race, belonging, survival, family, etc.
Afro-centrism is a term that is used to study the African race and anything related to that particular race. And among the characters of the story, the best character who exemplifies that character of Afro-centrism is Joseph Asagai.
Joseph is one of the suitors of Beneatha, the daughter of Mama Younger. He is proud of his Nigerian background and even tried to help Beneatha to accept and appreciate their African heritage. His desire is to go back home and help his people. Even though he's in America, he did not forget his roots and believed that he can help improve his people.
Thus, the correct answer is option B.
