Which of the following is an example of exclusive jurisdiction?

The correct answer illustrates a scenario involving exclusive jurisdiction, which is when a particular authority has sole control over a specific area or subject matter. In the context of military installations, such as Joint Base McGuire-Dix-Lakehurst (JB MDL), the federal government exercises exclusive jurisdiction. This means that the federal government has the authority to enforce laws and regulations within the installation without any interference from state laws.

Military installations generally operate under federal law, particularly concerning matters of security and operations, making it crucial for the military to have control over these areas to maintain order and security without state governance interferences. This exclusivity is particularly important for effective military operations and the handling of security issues that may arise within federal property.

In contrast, aspects such as state-owned lands, simultaneous authority of both state and federal on military installations, or the military having no jurisdiction would not correctly represent the concept of exclusive jurisdiction as they either blur the lines of authority or misplace the jurisdictional context between federal and state entities.
