I don't see the options you have in front of you, but this might be the likely answer:
It 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.
