One of functions of the legislature is to

Step 1: Analyze the question The question asks which option is a function of the legislature, the arm of government that makes laws (the National Assembly in Nigeria, made up of the Senate and the House of Representatives).

Step 2: Recall the three arms of government

• Legislature: makes laws, represents the people, controls finances (approves budgets), oversees the executive, and ratifies treaties and key appointments.
• Executive: implements or executes laws, and the President or Governor assents to bills.
• Judiciary: interprets laws and settles disputes.

Step 3: Test each option

• A. Execute laws: this belongs to the executive, so it is wrong.
• B. Assent to bills: the President signs a bill into law. This is an executive role, so it is wrong.
• C. Ratify treaties: the executive negotiates and signs treaties with other countries, but the legislature must approve or ratify them before they take effect. This is a legislative function, so it is correct.
• D. Interpret laws: this belongs to the judiciary, so it is wrong.

Step 4: Answer The correct option is C. ratify treaties.

Tip: Remember the pattern "Legislature = Law-making, Executive = Enforcing, Judiciary = Judging." Any option about approving, confirming, or ratifying (treaties, appointments, budgets) usually points to the legislature as a check on the executive.
