Answer:
The answer is option C "working with other countries through diplomacy"
Step-by-step explanation:
The term Foreign Policy can refer to a state’s international goals or agendas and its strategies to achieve those goals.
Diplomacy is the act of working with other nations, usually through negotiation and discussion. Diplomacy involves meetings between political leaders, sending diplomatic messages, and making public statements about the relationship between nations.
The US president, for example, often hosts leaders and chief diplomats of other nations at the White House in order to discuss a variety of issues.
Most diplomacy occurs behind the scenes as officials hold secret negotiations or meet privately to discuss key issues.
