Which of the following is a DHS agency?

• A. FEMA
• B. TSA
• C. Coast Guard
• D. USCIS

Answer: (B)

The main idea is recognizing which agencies fall under the Department of Homeland Security and how DHS organizes national security and emergency response. The Transportation Security Administration is the DHS agency tasked with aviation security, including passenger screening and setting security standards for air travel. But FEMA, the Coast Guard, and USCIS are also part of DHS, each with its own mission—FEMA coordinating disaster response and resilience, the Coast Guard handling maritime safety and security, and USCIS processing immigration services. Because all four options operate under DHS, the question as written has multiple correct examples. The key takeaway is that DHS oversees a broad range of agencies, not just a single one.
