Which of the following is a way the Department of State utilizes the economic instrument of national power?

The Department of State utilizes the economic instrument of national power primarily through actions like implementing tariffs and embargoes. This approach allows the government to influence other nations and promote national interests by leveraging economic policies. Tariffs can be used to regulate trade and protect domestic industries by making imported goods more expensive, thereby encouraging consumers to buy from local producers. Embargoes can restrict trade with specific countries to exert pressure, often for political reasons, influencing those nations' behaviors without direct military intervention.

The choices related to military operations, intelligence gathering, and facilitating military partnerships reflect other instruments of national power—namely, military and intelligence capabilities—rather than the economic strategies that the Department of State employs. Thus, implementing tariffs and embargoes is a clear example of how economic tools serve diplomatic objectives and are central to the Department of State's strategy in international relations.
