Question

which character is responsible for resolving the conflict, especially if it is internal?
protagonist
stock
antagonist

Explanation:

The protagonist is the central character in a story. In cases of internal conflict, which is a struggle within the character's mind, the protagonist is the one who has to face, process, and resolve it. Stock characters are more like stereotypes and not typically the ones resolving internal conflicts. The antagonist opposes the protagonist and causes external conflict rather than resolving internal ones.

Answer:

A. protagonist
