Final answer:
The Articles of Confederation created a unicameral Congress.
Step-by-step explanation:
The Articles of Confederation established a unicameral Congress as part of the governance structure of the United States. This means that the Congress had only one house instead of two, unlike the current bicameral Congress with the Senate and the House of Representatives. The Articles of Confederation did not create a court system or a president, so options B and C are incorrect.
