Final answer:
The structural elements included in the Articles of Confederation were the provision for a unicameral legislature, the designation of state sovereignty, and the absence of an executive branch.
Step-by-step explanation:
The framers of the Articles of Confederation incorporated several structural elements. These included B) The provision for a unicameral legislature. For instance, The Articles of Confederation authorized a unicameral legislature, a continuation of the earlier Continental Congress and there was no national judiciary (or Supreme Court) for the United States.
Another major element was C) The designation of state sovereignty. Before the ratification of the Constitution, the state governments' power far exceeded that held by the national government. The national government was limited, lacking both a president to oversee domestic and foreign policy and a system of federal courts to settle disputes between the states.
The framers also ensured D) The absence of an executive branch. There was no president or executive office of any kind under the Articles of Confederation. This was a conscious decision by the framers, seeking to avoid any potential tyranny from a single overly powerful individual.
