What term describes agreements between nations to aid and protect one another?

• A. Commerce
• B. Diplomacy
• C. UN (United Nations)
• D. Alliances

Answer: (D)

Mutual defense and aid agreements between nations are alliances. An alliance is a formal pact or treaty in which countries pledge to support each other, often in defense or security matters, in return for shared benefits and stability. This kind of arrangement creates a collective security framework—attack on one member can trigger help from all, as seen in organizations like NATO.

Commerce focuses on trade of goods and services between countries, not defense commitments. Diplomacy is the practice of negotiating and managing relationships between states. The United Nations is an international organization that facilitates cooperation and peacekeeping, not the specific term for a mutual defense agreement.
