Which jurisdiction is held only by the Federal government?

• A. Exclusive
• B. Concurrent
• C. Proprietary
• D. None

Answer: (A)

In federal systems, some areas are controlled exclusively by the federal government—only the federal level has the authority to regulate or adjudicate those matters. This is what exclusive jurisdiction means: it’s reserved for the national government and states can’t step in. The question is asking which type of jurisdiction fits that description, and exclusive is the one that means sole federal control.

Concurrent jurisdiction, by contrast, is shared between federal and state governments, which is not what’s being described here. Proprietary isn’t a standard category used to describe jurisdiction in this context, and None would imply there’s no exclusive federal domain at all, which isn’t correct because certain areas are indeed reserved for the federal government.
