A country's constitution may be derived from which one of the following sources?

1. Analyze the question The question asks about the sources of a constitution, meaning where its content and authority come from.

2. Explain the concept A constitution is the body of fundamental rules by which a country is governed. Its main sources include:

• Customs and conventions: unwritten practices and traditions accepted over time (the British constitution relies heavily on these)
• Statutes and legislation: laws passed by the legislature
• Judicial decisions: court rulings that interpret the law (case law)
• Written documents and treaties: charters, agreements, and earlier constitutions
• Constituent assembly or conference decisions: for example, Nigeria's constitutional conferences
• Religious laws: where applicable

3. Work through the options

• A. Educated elites: These are people or a social class. They may take part in drafting a constitution, but they are not a source of it.
• B. Civil society organisations: These groups may influence or lobby for constitutional change. They are not a formal source.
• C. Civil disobedience: This is a form of protest, not a source of a constitution.
• D. Customs and conventions: These are recognised sources. Accepted traditions and practices become part of a country's constitutional arrangements. ✔

4. Answer The correct option is D. Customs and conventions.

5. Tip For "sources of a constitution", think of C-S-J-C: Customs and conventions, Statutes, Judicial decisions, Constitutional conferences/documents. Options that name people or groups (elites, CSOs) or actions (protest) are usually distractors, because a source is a body of rules or practices, not a person or an activity.
