Detailed explanation-2: -Nash equilibrium in game theory is a situation in which a player will continue with their chosen strategy, having no incentive to deviate from it, after taking into consideration the opponent’s strategy.

Detailed explanation-3: -Nash Equilibrium represents an action profile for all players in a game and is used to predict the outcome of their decision-making interaction. It models a steady state (i.e., a combination of strategies of all players) in which no player can benefit by unilaterally changing its strategy.

Detailed explanation-4: -A Nash equilibrium in price competition occurs when each firm chooses its price, assuming its competitors’ prices will not change. In equilibrium, each firm is doing the best it can, conditional on its competitors’ prices.
