B. To regulate interstate commerce.
C. To define and punish offenses against the law of nations.
D. To advise and consent.
The correct answer is D. To advise and consent.
Explanation: The U.S. Constitution grants the Senate the role of “advising and consenting” to presidential nominations, including Supreme Court Justices, as outlined in Article II, Section 2. This means that the Senate has the authority to confirm or reject presidential appointments to ensure the nominees are qualified for their roles.
