• A. Department of Justice, Department of State
• B. Department of the Army, Navy, Marine Corps, and Air Force
• C. Department of Homeland Security, Department of Transportation
• D. Department of Education, Department of Health and Human Services

Answer: (B)

The correct choice identifies the primary components of the Department of Defense (DoD), which includes the Department of the Army, the Department of the Navy, the Department of the Marine Corps, and the Department of the Air Force. Each of these departments plays a critical role in national security and military operations. The Department of the Army is responsible for land-based military operations; the Department of the Navy oversees naval operations, which include both the Navy and the Marine Corps; and the Department of the Air Force handles air and space operations. This structure is essential for maintaining a coordinated and effective military force. In contrast, the other options list departments that do not fall under the purview of the Department of Defense and primarily focus on different governance areas, such as law enforcement, international relations, homeland security, and domestic welfare.
