Answer:
one player's optimal action choice taking the other player's action as given
Explanation:
The best response is a strategy from the game theory. This strategy holds that a player could select a strategy that favors him most given the strategies of other players. This is in reference to John Nash's Nash Equilibrium that explains that a player could reach that point(equilibrium) where he selects the best response or one of them that works best considering other players' strategies.
