Please help Which power is not specifically given to the president by the United States Constitution

A. Veto bills passed by Congress.

B. Serve as commander in chief of the country’s armed forces.

C. Raise or lower taxes on all Americans.

D. Pardon people convicted of federal crimes.

I pretty sure the answer is C. Raise or lower taxes on all Americans

Article 1 Section 1 of the U.S constitution states “All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives.” Article 1 Section 7 also states “All Bills for raising Revenue shall originate in the House of Representatives,” therefore meaning only the House of Representatives and other members of Congress can pass these laws.
