Step 2: Explain the concept Foreign policy is the set of goals, principles, and strategies a country uses to guide how it deals with other countries and international organizations. It covers things like diplomacy, trade, defence agreements, and membership of bodies such as the UN, AU, and ECOWAS. Its aim is to protect and promote the country's national interest abroad.

Step 3: Examine the options

• A. General principles that guide foreigners in a country: Wrong. Foreign policy is about how a country behaves toward others, not how foreigners behave inside it. That would be closer to immigration law.
• B. Policy made by a country during war: Wrong. Foreign policy applies at all times, not only in wartime.
• C. Policy made by a country in peace time: Wrong. It is not limited to peacetime either. It operates in both war and peace.
