Final answer:
Man vs. Self does not represent external conflict; it is an internal conflict where a character faces inner struggles, unlike Man vs. Man, Man vs. Nature, or Man vs. Society which involves external factors.
Step-by-step explanation:
The term that does not represent a type of external conflict is c. Man vs. Self. External conflicts involve a character facing challenges outside themselves. These include Man vs. Man, where characters are in conflict with one another; Man vs. Nature, where the character struggles against natural forces; and Man vs. Society, where the character is at odds with societal norms or laws. In contrast, Man vs. Self represents an internal conflict, where a character grapples with their own beliefs, emotions, or decisions.
