Answer:
B. Characters suffer due to personal flaws.
Explanation:
Tragedy is a genre of literature where the main characters suffer due to flaws they have individually or collectively. Such flaws might be dishonesty, hiding of a secret, greed, excessive display of love, stubbornness, etc.
The story of Romeo and Juliet is one such example of a literary piece marked by tragedy. The cause of the tragedy can be attributed to the excessive display of love by the young couple. This eventually led to their death and mourning for their respective families. A tragedy usually has a sad ending as was the case in this story.
