The answer is A) Raising taxes
The Constitution of 1789 gives the Federal Government authority to raise and levy taxes in all of the States in America.
It comes under the General Welfare Clause and gives complete authority to impose and collect taxes.
It prohibits separate State taxation IF it hinders inter State and International trading. It also prohibits each State from setting up independent import and export duties without the approval of the Federal Government, that is, the Congress.
It requires all tax revenue bills to originate solely from the House of Representatives.
