Ratification of treaties is by:

**The reasoning** Think of a treaty like a huge international agreement that affects the whole country. For it to become binding law, it must go through a democratic check. In Nigeria (and most democracies), **ratification of treaties** requires approval by the **Legislature** — the National Assembly (Senate and House of Representatives). Here's why: The Executive (President) may *negotiate* and *sign* treaties, but the Legislature must *ratify* them to ensure the people's representatives agree. This is separation of powers in action — preventing one branch from making massive commitments alone. Section 12 of the Nigerian Constitution backs this up. **Why the wrong options tempt you** **B) Executive only** — tempting because the President *signs* treaties, but signing isn't ratifying. Ratification needs legislative approval. **C) Police** and **D) Schools** — clearly irrelevant. They enforce laws or educate, but have zero role in approving international agreements. **Quick takeaway** "The Executive signs, but the Legislature ratifies" — just like your parents might discuss a family decision, but the whole household needs to agree before it's final!
