Which of the following is a non-governmental organization that participates in disaster relief efforts?

The Red Cross is widely recognized as a non-governmental organization that plays a significant role in disaster relief efforts. It operates independently of government entities and relies heavily on volunteers and donations to provide various services, including emergency assistance, disaster relief, and education. The organization is active in both local and international contexts, mobilizing resources and personnel to respond quickly to disasters such as natural disasters, humanitarian crises, and other emergencies.

In contrast, the Medical Reserve Corps and Public Health Departments typically function within the framework of government agencies and are often supported by government funding and resources. While they may provide valuable support during disaster situations, they do not classify as non-governmental organizations. The World Health Organization, although crucial in coordinating international health responses and policies, is a specialized agency of the United Nations and is therefore also not classified as a non-governmental organization.
