Capital of Nigeria.

**The reasoning** Nigeria's capital is **Abuja**. This changed in 1991 when the federal government officially moved from Lagos to Abuja. The relocation happened because Nigeria needed a centrally-located, neutral capital that didn't favor any particular ethnic group or region. Abuja sits in the middle of the country (Federal Capital Territory), making it geographically fair and accessible to all Nigerians. This is a **factual/historical knowledge** question — you either know it or you don't, but now you do! **Why the wrong options tempt you** - **Lagos** was the former capital (until 1991) and remains Nigeria's largest city and economic hub, so many still associate it with being "the main city" - **Kano** and **Ibadan** are major cities with large populations, but they've never served as the national capital **Quick takeaway** Remember: "**Abuja is Nigeria's capital since 1991 — centrally located for unity**." Lagos is the economic giant, but Abuja wears the political crown.
