Answer:
c) i and ii
Explanation:
Game theory looks at the interactions between participants in a competitive game and calculates the best choice for the player.
Dominant strategy is the best option for a player regardless of what the other player is playing.
Nash equilibrium is the best outcome for a player where no player has an incentive to change their decisions.
In this game, if both firms enter the market, they would both earn losses.
If one firm enters the market and the other doesn't, the firm that enters the market makes a profit of 100 while the other firm enters nothing
If both firms don't enter the market, they both earn nothing.
So, the possible equilibrium position is for one firm to enter the industry and for the other firm not to.
