Answer:
B. The Constitution established three strong branches of government.
Step-by-step explanation:
The Articles of Confederation created a strong legislative branch, a weak executive branch, and no judicial branch. The states themselves had judicial and executive branches, but on the national level, the Articles of Confederation really gave all the power to Congress, the legislative branch. There would be a President as an executive officer, but he was chosen from a Committee of the States that was appointed by Congress. The American colonists, in forming the new nation, had initially shown much concern about limiting any executive branch power, fearing it would become like the king of Britain had been in wielding excessive power.
The US Constitution would give the federal government significantly more powers than the Articles of Confederation had. And the Constitution made provisions for three coequal branches of the federal government to serve as a check and balance on one another -- the Executive, Legislative, and Judicial branches.
