Correct Option: B. Her national interests Detailed Explanation: Nigeria's voting at the United Nations (UN) is primarily guided by its national interests. This means that when Nigeria participates in UN discussions and votes on various resolutions, it considers what is best for its own country, including its political, economic, and social goals.

1. Understanding National Interests:
2. National interests refer to the goals and objectives that a country seeks to achieve in the international arena. For Nigeria, these interests can include economic development, security, regional stability, and the promotion of its influence in Africa and beyond.
3. Nigeria, being the most populous country in Africa and a significant player in regional politics, often aligns its UN votes with what it perceives will benefit its own national agenda.
4. Examples of National Interests in Action:
5. Economic Development: Nigeria may support resolutions that promote trade agreements or economic partnerships that could lead to investment in its economy.
6. Security Concerns: Nigeria has faced various security challenges, including terrorism and regional conflicts. Its voting may reflect a desire for international support in addressing these issues.
7. Regional Leadership: As a leading nation in the Economic Community of West African States (ECOWAS), Nigeria often votes in ways that reinforce its leadership role in West Africa.
8. Influence of Other Factors:
9. While other factors like concern for Africa (Option A), the Cold War (Option C), and world peace (Option D) do play a role in Nigeria's foreign policy, they are secondary to the overarching goal of protecting and promoting Nigeria's national interests.
10. For instance, Nigeria may support initiatives that promote peace in Africa, but this is often aligned with its own interests in maintaining stability in the region, which is crucial for its economic and political stability.

Why Other Options Are Weaker:

• Option A: Her concern for Africa:
• While Nigeria does have a strong commitment to African unity and development, this concern is often intertwined with its national interests. Nigeria's support for African initiatives is typically aimed at enhancing its own influence and ensuring regional stability, rather than purely altruistic motives.
• Option C: The Cold War:
• The Cold War was a significant period in global politics, but it primarily influenced international relations from the late 1940s to the early 1990s. Nigeria's current voting patterns at the UN are less about the ideological battles of the Cold War and more about contemporary issues that directly affect its national interests.
• Option D: World peace:
• While Nigeria does advocate for world peace and participates in peacekeeping missions, its voting decisions are often influenced by how these resolutions align with its national interests. Supporting world peace is important, but it is not the primary driver of Nigeria's voting behavior.

Revision Summary:

• Nigeria's voting at the UN is primarily guided by its national interests, focusing on political, economic, and social goals.
• National interests include economic development, security concerns, and regional leadership.
• Other factors like concern for Africa, the Cold War, and world peace are secondary to Nigeria's national interests.
• Understanding the motivations behind Nigeria's voting can provide insights into its foreign policy and international relations.
