The following are international organisations except

1. Analyze the question The question asks which option is NOT an international organisation. It is an "except" question, so three options are international organisations and one is not.

2. Explain the concept An international organisation is a body formed by member states (countries) to cooperate on political, economic, security, or social matters. Its members are sovereign countries, and it operates across national borders.

A pressure group is different. It is an association of people with shared interests who try to influence government policy without trying to take control of government. Examples are the Nigerian Medical Association (NMA), the Academic Staff Union of Universities (ASUU), and the Nigeria Labour Congress (NLC). Pressure groups are usually formed within a country, and their members are individuals, not states.

3. Step-by-step solution

• A. Pressure group: a group of citizens or professionals influencing policy. This is a general type of association, not an international organisation of states.
• B. O.A.U.: the Organisation of African Unity, formed in 1963 and now replaced by the African Union (AU). It is an international (continental) organisation.
• C. U.N.O.: the United Nations Organisation, a global body of states. It is an international organisation.
• D. Commonwealth of Nations: an association of mostly former British colonies. It is an international organisation.

Options B, C and D are all international organisations, so the odd one out is A.

4. Answer **A. pressure group.

5. Exam tip For "except" questions, group the options first. Here B, C and D are all bodies of member states, and A is the only one that is a type of group, not a specific organisation of nations. Remember that international organisations have countries as members, while pressure groups have individuals or professionals as members.
