Final answer:
When faced with deciding between two desirable outcomes, such as choosing between two great films to rent, this is known as an approach-approach conflict.
Step-by-step explanation:
The scenario of not being able to decide between renting one great film or another great film is described as a approach-approach conflict. This type of conflict occurs when a person must choose between two desirable outcomes that are mutually exclusive. In this case, the person wants to rent both movies, but can only choose one. The conflict arises because each film represents a positive and attractive option, but the limitations of time or resources force a single choice.
