Number of arms of government.

**The reasoning** The arms (or branches) of government are the **three separate divisions** that share power in a democracy. This is called the **principle of separation of powers**, designed to prevent any one group from becoming too powerful. The three arms are: 1. **Legislative** (makes laws) — e.g., National Assembly in Nigeria 2. **Executive** (enforces laws) — e.g., President and ministries 3. **Judicial** (interprets laws) — e.g., Supreme Court and other courts This structure exists at both federal and state levels in Nigeria. **Why the wrong options tempt you** - **Option A (2)**: You might think "government and courts" or confuse this with the two-party system. - **Option C (4)** or **D (5)**: You might be adding extra groups like "the military," "civil service," or "local government," but these aren't *arms* of government — they're either institutions *within* the Executive or levels of government (federal/state/local). **Quick takeaway** Remember **"LEJ"** — Legislative, Executive, Judicial — three arms always, in every democratic system including Nigeria's constitution.
