The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The president's constitutional powers give him world influence as well as a domestic influence because the President of the United States plays many key roles that grant him powers to efficiently and effectively do his job in the US and abroad.
The President of the United States is the head of the Executive branch. It is the most important figure of the nation and is the leader of the country. He is the Chief Diplomat, Commander in Chief, and Chief Executive, head of the state, and has the power to veto bills and return them to Congress. That is why he is the most respected man because he is the image of the country to other world leaders.
So as Chief diplomat he has the power to sign treaties and negotiate with foreign leaders and look for the benefit of the US economic and political interests around the world. As the head of the state, he can make tough decisions to protect the nation and create new opportunities for the American people.
Although the US President cannot declare war (that is a power of Congress) as the commander-in-chief he can send troops to other countries to exert pressure, protect people, or defend the interests of the country.
