Answer:
C. multilateralism
Step-by-step explanation:
Multilateralism is a foreign policy method that is based on cooperation and coordination among multiple countries. It aims to address global challenges and issues that cannot be solved by individual countries alone, such as climate change, terrorism, and poverty. By working together, countries can achieve common goals and promote peace, security, and prosperity for all. This approach is most likely to lead to international cooperation between countries, as it encourages collective action and shared responsibility.
