Final answer:
The Senate's power of advice and consent does not apply to impeachment trials.
Step-by-step explanation:
The Senate's power of advice and consent does not apply to c) Impeachment trials.
According to the Constitution, the Senate has the power to provide advice and consent for several important presidential powers, such as a) Presidential appointments, b) Ratification of treaties, and d) Confirmation of Supreme Court justices.
However, the Senate does not have the power to provide advice and consent in the case of impeachment trials. The House of Representatives has the sole power of impeachment, and it is the Senate's role to hold the trial and decide whether to convict or acquit the impeached official.
