Answer: b. Executive agencies receive their power delegated from the executive branch (the president). Independent agencies receive their power as delegated from Congress.
Explanation:
There are two types of Administrative agencies in the United States: Executive and Independent.
Executive agencies are created by the Presidency and are therefore answerable to the president. They usually have a single leader who sits on the President's cabinet.
Independent agencies are created by an Act of Congress to manage complex areas of operation. They do not usually have a single leader but rather a board or commission with leaders that do not sit on the President's cabinet. An example is the Environmental Protection Agency(EPA).
