In a game where both players have the option to cooperate or defect, which of the following scenarios represents a situation where each player's choice is their dominant strategy?

In game theory, a dominant strategy is one that is the best choice for a player, no matter what the other player decides to do. Consider a situation where two players can either cooperate, which means they work together for a mutual benefit, or defect, which means they act in their own self-interest. If both players choosing to defect leads to a better outcome for each player than if they cooperated, then defecting is their dominant strategy. For example, if Player A and Player B both get a payoff of 1 for defecting, but only 0. 5 if they both cooperate, then defecting is the best choice for both players.
