What does miss ophelia's purchase of topsy most clearly underline?
a. there is no such thing as a "good" slaveholder.
b. hypocrisy is everywhere.
c. christianity always triumphs in the end.

Miss Ophelia purchase from Topsy that hipocrisy is everywhere because when Saint Claire gives Miss Ophelia Topsy to educate her, she had discussed slavery several times before with Saint Claire, and eventhough Saint Claire knows that keeping slaves is wrong, she keeps doing it.
