Answer:
B). He’s upset with himself for making a promise he’s not sure he can keep.
Step-by-step explanation:
Conflicts are described as the clash or disagreement (which could be internal or external) of a character with the combatant forces. Internal conflict is illustrated as the 'clash or struggle' that occurs internally(in the mind) to the characters.
As per the question, the statement that best exemplifies Perseus's 'internal conflict' would include that 'he's upset with himself for making a promise he's not sure he can keep' as it reflects the psychological struggle of the character due to unfulfilled desires, beliefs, or emotions. It affects their internal experience and often leaves them shattered. Thus, option B is the correct answer.
