The accompanying matrix depicts two firms in a single-stage duopoly game.Each firm makes its decision without knowledge of the other firm's decision.The payoffs for each firm represent economic profits,and each firm strictly prefers more economic profit than less.If X is greater than $3,500,then:

A) there is only one Nash equilibrium,and this game would be considered a prisoner's dilemma.
B) there are two Nash equilibria,and this game would be considered a prisoner's dilemma.
C) there are three Nash equilibria,and this game would be considered a prisoner's dilemma.
