Federalism shares power between:

**The reasoning** Federalism is a system of government where power is **constitutionally divided** between two levels of authority. Think of Nigeria: we have the Federal Government in Abuja AND the 36 state governments. Neither can eliminate the other — both derive power from the Constitution. The key principle: **shared sovereignty**. The central government handles issues like defense, foreign policy, and currency, while component units (states) manage local matters like state education policies and local infrastructure. Both levels are independent within their spheres. **Why the wrong options tempt you** - **A) Two parties** — This describes a two-party system (like US Democrats vs Republicans), not how power is structured in government. - **C) Govt and citizens** — This describes democracy in general or civil rights, not federalism specifically. - **D) King and parliament** — This describes constitutional monarchy (like the UK), a completely different system. **Quick takeaway** When you see "federalism," think **vertical split**: national government at the top, state/regional governments below — both sharing power as constitutional partners, like Nigeria's three tiers working together.
