Win-set is a term coined by Robert Putnam in his famous article that he developed a framework for foreign policy decision-making (Putnam, 1988). According to Putnam’s framework, win-set of an actor can be defined as any desirable outcome from an international bargaining process. In other words, any outcome within the range of its win-set would be considered as gain by the actor. The formation of this win-set, according to Putnam, is directly related with the domestic political dynamics. Therefore, win-sets that determine the foreign policy agenda of a country is directly connected with the domestic politics of that country, according to Putnam’s framework. Therefore, the correct option is A.
