No, 4 is a power of the Supreme Court.

Congress is made up of the Senate and the House of Representatives. Congress is also known as the legislative branch of our government.
is it 1 then
Yes.

For the United States, Article One, Section Eight of the Constitution says "Congress shall have power to ... declare War." However, that passage provides no specific format for what form legislation must have in order to be considered a "declaration of war" nor does the Constitution itself use this term.
