Step-by-step explanation:
Among the options provided, TRICARE is the healthcare program that covers veterans of the U.S. armed forces. TRICARE is a Department of Defense healthcare program intended to provide medical care for retired military personnel and their families, as well as some members of the Reserves and National Guard. While other options like Medicaid, Medicare, and private insurance may also cover veterans depending on their circumstances, TRICARE is the program specifically designed for military personnel.
