Which of the following is NOT a responsibility of the TSA?

The correct choice highlights that collecting air traffic data is not a responsibility of the Transportation Security Administration (TSA). Instead, the TSA's primary focus is on ensuring transportation security, particularly regarding aviation. This includes conducting security screenings for passengers and baggage, overseeing the implementation of security policies, and making certain that airport operations comply with safety regulations.

While collecting data on air traffic can be related to safety and operational management, it falls under the purview of other entities involved in air traffic control and management, such as the Federal Aviation Administration (FAA). Therefore, this distinction clarifies the TSA's specific role in the aviation industry, which is more aligned with security measures rather than traffic data collection.
