In the United States of America, legislature is called the

Step 1: Analyze the question The question asks for the name of the legislature (the law-making body) of the United States of America.

Step 2: Explain the concept A legislature is the arm of government that makes laws. Different countries give it different names:

• USA: Congress
• Nigeria: National Assembly
• United Kingdom: Parliament
• Ghana: Parliament

The US Congress is bicameral (has two chambers):

1. Senate (upper house), with 2 senators from each state, so 100 in total
2. House of Representatives (lower house), with seats allocated by state population, 435 in total

Step 3: Evaluate the options

• A. Congress: Correct. This is the official name of the US legislature, created by Article I of the US Constitution.
• B. National Assembly: This is Nigeria's legislature (Senate plus House of Representatives), which is modelled on the American system. It is not the US name.
• C. National Security: This is not a legislature at all. It refers to protecting a country's safety.
• D. Parliament: This is used in the UK, Ghana, Canada and others, not in the USA.

Step 4: Answer The correct answer is A. Congress.

Tip: Link each country to its legislature: USA = Congress, UK = Parliament, Nigeria = National Assembly. A quick way to remember is "Congress for Capitol Hill" in Washington, D.C. Nigeria also copied the American two-chamber structure, which is why the two are often confused in exams.
