**The reasoning**
Nigeria's economy has transformed significantly over the past two decades. While many people still think of Nigeria primarily as an agricultural or oil-producing nation, **the Services sector now dominates our GDP, contributing over 50%**. This sector includes telecommunications, banking, insurance, entertainment (hello, Nollywood!), hospitality, real estate, and retail trade. Think about all the banks, phone networks, and tech startups around you — that's Services at work.
**Why the wrong options tempt you**
**Agriculture (A)** — Our history! Cocoa, groundnuts, palm oil built old Nigeria, but Agriculture now contributes around 25% of GDP, though it still employs the most people.
**Mining (D)** — Oil exports dominate headlines and foreign exchange, but extractive industries contribute only about 10% to GDP nowadays.
**Manufacturing (C)** — Still relatively small in Nigeria, under 10%, despite industrialization efforts.
**Quick takeaway**
Nigeria's economy runs on services — from your mobile data to bank apps — not just farms or oil wells anymore.
