b. can appoint officials to the federal bureaucracy with the approval of the Senate

Explanation:

The US president has the prerogative of appointing officials to various positions in the state bureaucracy, with the consent of the Senate. The fact that the Senate has to approve is a way to prevent the president from nominating people who are not properly qualified or who are submissive to the president. For example, the president nominates an economist to head the Federal Reserve, and that economist will be sabbathed and approved by the Senate, which will ascertain the economist's technical qualifications and ability to work independently.
