Final answer:
Option (D), The U.S. Constitution solved a problem created by the Articles of Confederation by granting the federal government the authority to collect taxes, enhancing the government's ability to generate revenue and function effectively.
Step-by-step explanation:
The U.S. Constitution addressed a critical shortcoming of the Articles of Confederation by enabling the federal government to collect taxes. Under the Articles, the federal government lacked the power to tax the states directly, which significantly limited its ability to raise revenue and fund the government.
The Constitution rectified this by creating a stronger central government with the power to levy taxes, thus solving one of the economic problems that the Confederation faced and creating the means for a more stable and effective national government.
