Final answer:
The majority of U.S. governors have the power to A. negotiate treaties with foreign nations, which the president does not have.
Step-by-step explanation:
The correct answer is A. negotiate treaties with foreign nations.
Although both the U.S. president and governors have significant powers, governors have the power to negotiate treaties with foreign nations that the president does not have. The president has the power to negotiate treaties, but they must be ratified by a two-thirds vote of the Senate.
For example, if a governor of a state wants to negotiate a trade agreement with a foreign country, they can directly engage in those negotiations on behalf of their state and reach an agreement without the need for Senate ratification.
