Answer:
Option C, "Have little direct control over their actions after they have been appointed by the president and confirmed by the Senate," is the most accurate statement regarding the President's control over Independent Agencies.
Independent Agencies are established by Congress to carry out specific tasks that are deemed to be outside the scope of regular executive branch agencies. Examples of independent agencies include the Federal Reserve, the Securities and Exchange Commission, and the Environmental Protection Agency.
While the President has the power to appoint the heads of many independent agencies, their terms are typically set for a fixed period of time and are not subject to removal by the President except for cause. This means that once appointed, agency heads have a degree of independence from presidential control and are free to carry out their duties without direct interference from the President.
While the President may be able to influence the direction of an independent agency through the appointment process, budgetary control, and other means, the President's control over independent agencies is generally limited by law and the Constitution.
