Answer:
B. Inability to tax citizens
Step-by-step explanation:
Immediately after the American Revolution, the Articles of the Confederation gave little power to the federal government, for fear of a tyrannical government, such as that of the British Empire that the American state had just evaded through the Revolution.
In consequence, because of lack of power over the states, the federal government could hardly collect taxes and this created huge economical issues at a central level.
The other answers are not correct, because the Articles of the Confederation gave the federal government power to make foreign policy, establish land ordinances and negotiate treaties with Native Americans.
