Answer:
The correct answer is option c.
Step-by-step explanation:
Prisoner's dilemma is a common concept in the game theory. It shows why two rational individuals will not cooperate. Two prisoner's have the choice to cooperate with each other and remain silent or blame the other.
The Nash equilibrium for both the payers here will be to betray each other. But this will incur cost on both of them. If the players could cooperate with each other, they would not agree to this.
