What types of property can security guards protect?

The correct choice reflects the broad scope of property types that security guards are tasked with protecting. Commercial properties encompass businesses and retail locations, where security is vital to prevent theft and ensure customer safety. Residential properties involve homes and apartment complexes, where private security can help maintain peace and deter crime among residents.

Public properties refer to spaces owned by governmental entities, such as parks, libraries, and municipal buildings, which require protection to ensure the safety of the public and the preservation of public resources. The combination of these categories highlights the versatility and importance of security services across various environments, as each type of property may have different security needs and challenges.

Although the other options mention valid property types—such as industrial or government buildings—they do not capture the full breadth of locations where security guards typically operate. The chosen answer encapsulates the diverse settings in which security personnel play a crucial role in maintaining safety and security for both people and property.
