Answer:
Character vs Self.
Step-by-step explanation:
Internal conflict exemplifies the internal struggle of a character which may include an emotional clash, fear or abandonment contrary to the external conflict that illustrates a clash between an individual and an outside force(society, nature, etc.)
Internal conflict displays a psychological clash into the mind of the characters that reveals the inherent flaws of the characters which make the plot more lifelike and assists to inculcate suspense and evoke an emotional and sympathetic response from them. Thus, character vs self best demonstrates the internal struggle that could be opposing psychological beliefs, impulses, desires or feelings in a character's mind.
