The power to nominate federal judges is not a congressional power; it is a power of the President of the United States. The Constitution gives the President the power to nominate Supreme Court Justices and other federal judges, although these nominations must be confirmed by the Senate.
Here's a breakdown of the options you provided:
a. Lay and collect taxes - This is a power of Congress, specifically granted by Article I, Section 8 of the Constitution.
b. Raise and support an army - This is also a power of Congress, found in the same section of the Constitution.
c. Declare war - This is another congressional power, as only Congress has the authority to declare war under the Constitution.
d. Nominate federal judges - This is not a power of Congress; it is a power of the Executive branch.
