The perceived perennial problem of the United Nations (UN) since its inception is the

Analyze the question: It asks about the long-standing (perennial) problem facing the United Nations since it was founded in 1945.

Explain the concept: The UN brings together almost every country in the world. These countries differ in ideology (capitalism vs. communism during the Cold War), religion, culture, economic strength, political systems and national interests. Because of this, members often disagree on key issues such as peacekeeping, sanctions, human rights and the use of force. The veto power of the five permanent Security Council members (USA, UK, France, Russia, China) often makes these disagreements worse. Other recognized UN problems include funding difficulties and the lack of an army of its own, but the root of most of them is the differing interests and backgrounds of its members.

Solution (checking each option):

• A. Directive Principles of State Policy: This is a part of the Nigerian Constitution (Chapter II). It is a national matter and has nothing to do with the UN's problems as an organization. ❌
• B. Deep-seated diversity among member states: This fits. Differences in ideology, interests, culture and power cause deadlock and make consensus hard. ✅
• C. Nature of political leaders and their ages: The ages of leaders is not a recognized problem of the UN. ❌
• D. Poor constitutional provisions of member states: Each country's constitution is its own internal affair, not the UN's perennial problem. ❌

Tip: For Government questions on international organizations (UN, AU, ECOWAS, Commonwealth), the common recurring problems are differences in interests/ideology among members, inadequate funds, and big-power dominance (veto). When an option mentions a national constitution or Nigerian-only concepts such as Directive Principles, it is usually a distractor.
