C.The federal government was able to collect taxes.
Under the Constitution, the government consists of three branches (Legislative, Executive and Judicial), in which the Legislative has the power to lay and collect taxes. This was quite different under the Articles of Confederation, which established a weak central government that consisted only of a Congress. One of the most important powers the Congress lacked was the power to collect taxes, therefore if they needed to raise money, they could attempt to do so by asking the states for funds (which had the option to reject the request), borrowing from foreign governments, or selling western lands.
