Which of the following is NOT a function of the Transportation Security Administration (TSA)?

The correct choice identifies that regulating airline ticket prices is not a function of the Transportation Security Administration (TSA). The TSA is primarily focused on security measures and protocols to ensure the safety of travelers and transportation systems in the United States. Its main responsibilities include preventing hijackings, developing airport security policies, and ensuring safety within U.S. transportation infrastructures, such as airports and other transit points.

Regulating airline ticket prices falls under the purview of different entities, such as the Department of Transportation (DOT) and the airline industry itself, which operate under market regulations rather than security protocols. This clarification helps establish a clear understanding of the specific roles and responsibilities of the TSA versus other governmental agencies involved in transportation economics and regulation.
