Step 1: Analyze the question The question asks which activity the Commonwealth of Nations is concerned with in its member countries.

Step 2: Explain the concept The Commonwealth of Nations is a voluntary association of mostly former British colonies, including Nigeria, Ghana, and India. Its aims include:

• C. Operating the financial sector of poor countries: Wrong. This is closer to the role of bodies like the IMF and World Bank.

Exam tip: For questions on international organizations, eliminate options involving "overthrow," "conducting elections," or "operating finances." Organizations like the Commonwealth, AU, and ECOWAS typically promote or support ideals such as peace, democracy, and development. They rarely take over a state's own functions.
