Answer:
the best answer is D, collecting taxes
Step-by-step explanation:
the states, not the central government, was given the power to collect taxes
the rest of the powers that the Articles of Confederation gave were more relevant to war and diplomacy and had nothing to do with the other answers, so this is the only one that is logical
(though it definitely is a tricky question thats worded quite weirdly i can see why you went on here for help bc id do the same thing)
Hope this helps :)
