Answer:
The correct answer is letter "C": An argument that the domestic and international role of the presidencies are distinct.
Explanation:
The concept of dual presidency is based on the principle that there are two images of the American president: one about domestic politics and one about foreign politics. It was proposed by American political scientist Aaron Wildavsky (1930-1993). According to Wildavsky, presidents prefer to center their attention in international policies because those grant them more authority than when compared to their domestic policies.
