Which department's restructuring aimed at improving national security by consolidating multiple agencies under one umbrella?

• A. Department of Defense
• B. Department of Justice
• C. Department of Homeland Security
• D. Department of Energy

Answer: (C)

Consolidating multiple agencies under one umbrella to boost national security hinges on improving coordination across border control, immigration, transportation security, and emergency response. After 9/11, the government created the Department of Homeland Security to bring several agencies with overlapping safety and security responsibilities into a single cabinet-level department. The idea was to streamline leadership, standardize procedures, and accelerate information sharing so that threat detection and disaster response could be more coordinated and timely. DHS combines functions that handle things like border protection, immigration enforcement, aviation and transportation security, and emergency management, creating a unified approach to domestic security. The other departments have more specific or different focuses—defense abroad, justice and federal law enforcement, or energy and nuclear security—without the same broad domestic security and disaster-response mandate under one roof.
