Answer:
The correct answer is option A.
Step-by-step explanation:
In the case of non-fiction, the central idea is the most important message that the writer conveys. One of the central ideas of “I Know Why the Caged Bird Sings” by Maya Angelou says that "People without much education can be as wise as well-educated people". The poem is a reflection of the poet’s and her brother’s struggle and fight against racism. It is how with little opportunities, abuse but with experience they turned out to be wise people.
