Answer:
A. The president sets foreign policy and meets with world leaders.
Step-by-step explanation:
Foreign policy is defined as the set of public decisions made by the government of a State based on national interests and in relation to the other actors of a country's international system. It can also be defined as an area of government activity that is conceived between State relations with other factors. It is the external variable of the project that every Nation defines at a certain moment of its historical development. As an integral part of a national project that a country has, foreign policy must respond, in the first place, to the aspirations for peace and security and to the political, economic and social development needs of the country. This reflects the strength of a State, integrated as a nation, with a stable government and with a sovereignty deposited in the citizens and expressed by its representatives through the national interest.
