What is the term for an agreement among countries to support or defend each other?

• A. Treaty
• B. Alliance
• C. Pact
• D. Coalition

Answer: (B)

An alliance is a formal agreement between countries to cooperate and defend one another, forming a security partnership. It emphasizes mutual support in defense and common security goals, often with long-term commitments. While a treaty is a binding agreement between states and a pact is a broader term for an agreement on various topics, and a coalition is typically a temporary group formed for a specific purpose, the concept described—mutual defense and ongoing cooperation—best fits an alliance. For example, NATO is a well-known defense alliance.
