Which phrase describes a policy with the goal of keeping a country safe from attack or harm?

• A. Environmentalism
• B. NAFTA
• C. Global communication
• D. National security

Answer: (D)

The main idea here is understanding what kind of policy aims to keep a country safe from attack or harm. National security is the term used for policies and actions that protect a nation—its people, government, and territory—from threats such as military aggression, terrorism, espionage, cyber attacks, and natural disasters. It encompasses defense, intelligence, border controls, emergency preparedness, and diplomatic efforts all aimed at maintaining sovereignty and safety. That direct focus on safeguarding the nation from harm is why this phrase fits the description best.

Environmentalism centers on protecting the environment and natural resources, not national safety from threats. NAFTA is a trade agreement designed to promote economic exchange among the U.S., Canada, and Mexico. Global communication refers to sharing information across borders, which influences international relations but does not itself define protection from attack.
