Correct Option: C. Developing countries Detailed Explanation: Understanding South-South Cooperation: South-South cooperation refers to the collaborative efforts between countries in the Global South, which primarily includes developing countries. This cooperation is aimed at sharing knowledge, skills, and resources to achieve mutual development goals. The concept emerged as a response to the need for developing countries to work together to address common challenges, such as poverty, economic development, and social issues, without relying solely on assistance from developed countries. Why Option C is Correct: 1. Focus on Developing Countries: Nigeria, as a developing country, engages in South-South cooperation primarily with other developing nations. This cooperation is based on shared experiences and challenges, making it more relevant and effective for countries at similar levels of development. 2. Mutual Benefits: The relationships formed through South-South cooperation allow for the exchange of best practices, technology transfer, and capacity building among developing countries. Nigeria has actively participated in initiatives that promote trade, investment, and cultural exchange with other developing nations. 3. Policy Framework: Nigeria's foreign policy emphasizes strengthening ties with other developing countries to enhance economic growth and development. This is evident in Nigeria's participation in various regional and international organizations that focus on the interests of developing nations. Why the Other Options are Wrong or Weaker:

• Option A: Developed countries
• Reasoning: While Nigeria does engage with developed countries, this does not fall under the umbrella of South-South cooperation. The term specifically refers to collaboration among developing countries. Relations with developed countries often involve aid and assistance rather than mutual cooperation based on shared development experiences.
• Option B: Countries of the southern hemisphere
• Reasoning: This option is misleading because it implies a geographical focus rather than a developmental one. Not all countries in the southern hemisphere are developing countries (e.g., Australia and New Zealand are in the southern hemisphere but are developed). South-South cooperation is specifically about developing countries, regardless of their geographical location.
• Option D: Member countries of OAU (Organization of African Unity)
• Reasoning: While the OAU (now the African Union) includes many developing countries, South-South cooperation is broader than just African nations. It encompasses cooperation among developing countries globally, not limited to those in the OAU. Therefore, this option is too narrow and does not accurately represent the scope of South-South cooperation.

Summary of Key Points:

• South-South cooperation focuses on collaboration among developing countries to address common challenges.
• Nigeria's foreign policy emphasizes strengthening ties with other developing nations for mutual development.
• The correct answer is C, as it accurately reflects the nature of South-South cooperation.
• Other options are incorrect due to their focus on developed countries, geographical misinterpretations, or limited regional scope.

This understanding of South-South cooperation is crucial for grasping Nigeria's foreign relations strategy and its commitment to fostering development through partnerships with other developing nations.
