To understand how domestic factors create an impact upon foreign policy, what needs to be done is to classify the major political actors in domestic politics which are available as summarized below:

Domestic Actors

• The executive branch of government
• The legislative branch
• The judicial branch
• Political parties, their factions and wings
• Businesses and business coalitions
• Political action groups
• Domestic interest groups
• The media
• Unions
• State governments
• Powerful/influential individuals, such as the Senate majority leader, former presidents, etc.
• Epistemic communities, such as environmental scientists
• Religious groups
• Criminal and terrorist forces (domestic)

Non-domestic Actors

• Other nation-states
• Treaty alliances
• Multinational corporations
• International nongovernmental organizations
• Intergovernmental organizations
• Trans-governmental coalitions
• Foreign media
• Foreign powerful/influential individuals
• Foreign epistemic communities
• Foreign courts
• Foreign criminal and terrorist forces

(Hudson, 2013, p.144-5)

As also understood from the list given, the correct answer is D. “The legislative branch”, “The judicial branch”, “State governments” and “Political action groups” are among the major political actors in domestic politics, on the other hand “Treaty Alliances” can be given as an example of non-domestic major political actors in domestic politics.
