What is the full form of TSA?

The correct answer, Transportation Security Administration, is the full name of the U.S. government agency responsible for ensuring the security of the nation's transportation systems. This includes overseeing security measures at airports, railways, and other modes of transportation to protect the public from threats, such as terrorism. The agency was created in response to the events of September 11, 2001, and its mandate has since expanded to cover various aspects of transportation safety and security.

In contrast, the other options do not reflect the accurate title or scope of the organization. For example, Transportation Security Authority suggests a governance body but mislabels the agency, while Transport Safety Agency and Travel Safety Administration do not capture the full name or specific mandate of the agency. Understanding the correct terminology is crucial for identifying the roles and responsibilities of federal agencies related to transportation security.
