Answer:
C. Raise or lower taxes on all Americans
Step-by-step explanation:
According to the constitution , the power to raise or lower Taxes is held by the members of the Congress, not the president.
This line can be seen in Article I, Section 8 of the constitution which stated that: 'The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises'
Under the constitution, the president can only make a proposal/suggestion to the Congress. But in the end, Congress is the one that make the final call to legalize it.
