The Articles of Confederation granted the national government powers to do such things as declaring war, appoint military officers, manage relations between Indians, create alliances between other countries, sign treaties, and appoint foreign ambassadors. Which would mean the answer should be option D "the ability to set foreign policy." Which is because the Articles of Confederation has nothing to do with the ability to tax, and print paper money. (options B, and C) When it comes down to options A, and D the answer wouldn't be option A because the Articles of Confederations says nothing about trade. Therefore the answer would be D.
Hope this helps.
