B. a process in a tragedy in which a character heals, often through a painful realization
Explanation:
A cathartic experience is one that gives some type of emotional release. In literature, the character has this release as a result of a painful experience that helps them realize something about themselves. The word comes from the Greeks, it's original meaning purification.
The best revision is: "I am interested in drawing, painting, and making sculptures". You have to edit "make" into "making" as all the other actions in the sentence are verbs.
