Answer:
The answer is A. Benvolio is a flat character.
Step-by-step explanation:
Flat characters are simple characters that don't change throughout a work of fiction and are usually used to move the plot forward.
Round characters, on the other hand, grow and develop as a result of the events depicted in the text. This is mostly true for main and secondary characters.
In "Romeo and Juliet," Benvolio is a loyal and sympahtetic character that remains that way until the end, without undergoing any changes. Therefore, he is considered a flat character.
