Final answer:
When two or more incompatible motivations within an individual compete for expression, it is known as internal conflict, which is common in both real life and literature.
Step-by-step explanation:
The struggle that occurs when two or more incompatible motivations compete for expression is known as internal conflict. This kind of conflict takes place within an individual when they are faced with conflicting morals, emotions, or desires. For example, a person might experience internal conflict when they have to choose between a moral obligation to their family and a personal ambition that requires sacrifice of family time. Similarly, in literature and drama, characters often struggle with internal conflicts as they navigate personal dilemmas or moral quandaries. Such conflicts are fundamental to character development and plot progression, presenting the character's deepest struggles as they decide which path to take.
