Answer:
D because it corresponds in some way
Explanation:
The excerpt given above is taken from Phillis Wheatley's poem "On Being Brought from Africa to America". The word sable literally means color black. In this line, Wheatley uses the word "sable" to indicate sense of inferiority. The author is an African and their race color is different from the rest.

Hey there! I'm happy to help!
A round character is one that we have a lot of detail on. A flat character is one that we do not know much about (things like backstory, feelings, etc.)
Usually the round character is the main character. Out of these answer options, Camilla looks like the main character because stories usually aren't focused on villains (B and D) and Cecilia seems like more of a side character, so I believe Camilla is the main character.
She also seems the most round because it says that she is from Gaul and she wants to make a new life in Rome. We already have much more backstory to her than the others, so the the round character is A. Camilla, the stranger from Gaul who is trying to make a new life in Rome.
Have a wonderful day! :D
