Answer:
c. He sparks Beneatha's interest in Africa.
Step-by-step explanation:
Asagai is one of Beneatha's suitors. He comes from Nigeria, and therefore, is able to provide a different perspective on the experiences of black people. He lightly criticizes Beneatha's acceptance of white dominance, and this sparks in her a new understanding of her heritage. It is implied that she will marry Asagai and move back to Nigeria with him.
