Acabinet department head is appointed by the president but must be confirmed by which of the following?

A Cabinet department head is appointed by the United States President, but his position must be confirmed by the Senate of the United States. This rule comes from the Appointments Clause of the United States Constitution (Article II, Section 2, Clause 2).
