Capital of Nigeria.

**The reasoning** Nigeria's capital is **Abuja**, and this has been the case since December 12, 1991. Before then, Lagos was the capital. The government deliberately moved the capital to Abuja because of its central location in the country — it's easier to govern from the middle than from one corner. Abuja is in the Federal Capital Territory (FCT), purpose-built to be neutral ground, not favoring any particular region or ethnic group. **Why the wrong options tempt you** - **Lagos** was the old capital and is still Nigeria's largest city, busiest port, and commercial hub — so many students assume it's still the capital. - **Kano** and **Ibadan** are major cities (Kano in the North, Ibadan in the Southwest), but they've never been national capitals. Their size and importance can confuse students who haven't studied this carefully. **Quick takeaway** **Lagos was yesterday's capital; Abuja (since 1991) is today's.** Remember: Lagos = commerce, Abuja = government.
