Final answer:
In the auction scenario, there is one Nash equilibrium - for both firms to bid $6,000. This is the strategy that maximizes the profit for both firms.
Step-by-step explanation:
The correct statement that accurately describes the scenario in the auction is B) There is one Nash equilibrium - for both firms to bid $6,000.
In a Nash equilibrium, neither player has an incentive to change their strategy given their opponents' strategy. In this case, if Firm A bids $6,000, it maximizes its profit regardless of Firm B's bid. If Firm B bids $6,000, it also maximizes its profit. Therefore, both firms have a dominant strategy of bidding $6,000, which is the Nash equilibrium.
This scenario assumes that the firms are purely self-interested and do not trust each other. It does not consider possible cooperative strategies or trust.
