Answer:
The correct answer is letter "B": the best strategy to pick, no matter which moves are chosen by the other player.
Step-by-step explanation:
Game theory is used in mathematics and economy to explain how individuals make their choices. All participants in a game use some sort of strategy that allows them to have chances of winning the game. Under such circumstances, a dominant strategy refers to one specific approach that leads to absolute best effects regardless of the choices that the other participants may select.
However, sometimes there are no dominant strategies in a game. Therefore, participants must adapt to the moves of other players to find a way to outstand.
