Which term describes a mutually beneficial relationship between two individuals?

• A. Superego
• B. Projection
• C. Symbiosis
• D. Regression

Answer: (C)

A mutually beneficial relationship between two individuals is described by symbiosis. This term comes from biology, where it refers to two different organisms living together in a way that benefits both. For example, certain fungi and algae partner to form lichens, and gut bacteria help digestion while thriving in the host. The idea carries into interpersonal contexts as well, describing close relationships where both people gain something—support, resources, companionship, or growth. The other terms point to internal processes: the superego embodies moral rules, projection is about shifting one’s own feelings onto others, and regression is reverting to an earlier developmental state under stress. So the best fit for a mutually beneficial relationship is symbiosis.
