Which of the following stands for the People Access Security System?

The correct answer is PASS, which stands for People Access Security System. This term refers to a system designed to manage and control access to secure areas, ensuring that only authorized individuals can enter sensitive locations. In the context of immigration and security protocols, such systems are vital for maintaining integrity and safety within facilities.

Other options, such as PAS, PAU, and PCII, do not represent the People Access Security System. PAS might seem relevant as it shares similar letters, but it does not correspond to the defined acronym. PAU and PCII are entirely different terms that refer to different systems or concepts within the security or immigration framework, further illustrating that PASS is the specific and correct terminology associated with access security systems.
