Answer: D. executive orders.
The Senate power of advice and consent is used to checkmate discrepancies and other major activities that take place in the legislative and executive arms of government. Besides having the right to confirm major presidential appointments, the senate also has the right to advise and consent on appointments of positions such as ambassadors, the chief justice, and federal judges.
This power enables the Senate to approve certain governing processes by a vote of two-thirds or a majority of the senators. However, it does not apply to signed and published presidential directives (executive orders).
