Which of the following behaviors is prohibited on federal property?

Loitering and disorderly conduct are prohibited behaviors on federal property because they can disrupt the security and safety of the environment. Federal properties are designed to maintain order and ensure the safety of employees and visitors. Allowing individuals to loiter or engage in disorderly behavior can pose a risk to others and undermine the purpose of maintaining a secure, professional atmosphere.

In contrast, eating and drinking beverages, talking on mobile phones, and using public transportation are generally acceptable behaviors in many federal settings, provided they are done in a manner that does not interfere with official duties or disrupt the surroundings. These actions are not inherently problematic as they do not typically compromise safety or order, which differentiates them from loitering and disorderly conduct.
