Final answer:
The Education Division is not one of the FBI's functional areas. The other mentioned divisions, Cyber, Intelligence, and Counterterrorism, are official parts of the FBI's structure. The FBI operates within constitutional limits, including the Fourth Amendment.
Step-by-step explanation:
The federal law enforcement agency within U.S. national borders is known as the Federal Bureau of Investigation (FBI). Among its several functional divisions, the ones officially recognized include the Cyber Division, Intelligence Division, and Counterterrorism Division. However, the Education Division is not one of the FBI's five functional areas. The FBI's roles and activities, such as the response to cyber threats, intelligence gathering, and counterterrorism efforts, are critical to national security but must align with constitutional protections like the Fourth Amendment.
