3. In paragraph 18, why does the author follow the line, “People did right then,” with, “Oh look at the cute little pickaninny!

B.

Explanation:

'A Good Man Is Hard To Find' is a short story written by Flannery O’Connor. The story centers on the themes of  grace, Christian beliefs, moral conduct, etc. These themes are represented in the story with the tone of humor and irony, by the author.

In the story, in paragraph 18, the author followed the line 'People did right then' with ' "Oh look at the cute little pickaninny!" was to reveal the grandmother's hypocrisy. Using the derogatory term 'pickaninny' grandmother tried to portray the young black child to nothing. These lines also suggests how she glorified the past of South when blacks were treated like nothing and confer it as a 'right thing that people did back then.'

Thus, these lines are used by author to portray hypocrisy of the grandmother. Therefore, option B is correct.
