Which of the following individuals is authorized as a peace officer?

The correct answer is that airport security personnel commissioned as peace officers are authorized as peace officers. This is because these individuals have undergone specific training, are often certified, and are given legal authority to enforce laws and maintain order within their jurisdiction, typically in transportation hubs like airports. They possess the power to carry out law enforcement duties, including arresting individuals when necessary.

Authorized peace officers play a crucial role in ensuring the safety of the public, particularly in high-traffic locations like airports where security is paramount. Their commissioning as peace officers gives them specific rights and responsibilities that are not available to other types of personnel in security roles.

In contrast, personal trainers and unarmed private security guards do not possess the legal authority or law enforcement powers associated with being a peace officer. While they may contribute to safety and security in their respective domains, they lack the formal authority to act as law enforcement agents. Peacekeeping soldiers operate under different mandates and are often involved in military or international operations rather than the law enforcement duties assigned to peace officers.
