The term “Prisoner’s Dilemma” is associated with which one of the following?

The “Prisoner’s Dilemma” is a canonical example from game theory describing a situation in which two rational individuals, acting in their own self-interest, obtain worse outcomes than if they had cooperated. In the classic formulation each prisoner must choose to cooperate (stay silent) or defect (betray); mutual cooperation yields a better joint payoff, but individual incentives make defection the dominant strategy, producing a suboptimal equilibrium. The concept is widely used to study strategic interaction, cooperation, and conflict in economics and related fields, and has been analyzed in both its one-shot and iterated (repeated) forms in game-theoretic literature.
