Which statement correctly assigns the Navy's defense role?

• A. The Space Force provides guardians to conduct space operations.
• B. The Army is the only branch with a dual mission.
• C. The Navy defends freedom, preserves economic prosperity, and keeps the state open and free.
• D. The Joint Staff is composed of all service branches.

Answer: (C)

The main idea tested here is how the Navy’s role fits into national defense by protecting the freedoms and economic lifelines that underwrite national security. This statement best captures that role by framing the Navy as defending freedom, preserving economic prosperity, and keeping the state open and free—concepts that hinge on secure maritime trade and open sea lanes. Naval power supports deterrence, sea control, and power projection to safeguard international commerce and respond to crises at sea or abroad, which in turn helps ensure the country’s security and prosperity. The Space Force handles space operations, not naval duties; the Army isn’t uniquely dual-missioned, and the Joint Staff’s composition is about cross-service coordination rather than defining the Navy’s defense role, so those descriptions don’t fit as well.
