Answer:
The correct answer is B. Executive departments main purpose is to provide the president with information, administer programs, and carry out the laws instituted by Congress in their particular area.
Explanation:
An executive federal department is mandatorily created by congressional law, and not by decision of the head of state or government. The chiefs of the US executive departments, known as secretaries of this department, form the traditional United States Cabinet (or presidential cabinet), an executive body at the disposal of the President of the United States and which normally acts as a structure Council of the Presidency.
Since 1792, by statute, the members of the cabinet constitute a presidential order of succession, after the Speaker of the House of Representatives and the president pro tempore of the Senate in case of vacancy of both the presidency and the vice-presidency. The US Constitution refers to these department secretaries when it authorizes in Article II, Section 2 to "require the Opinion, in writing, of the Principal Officer in the Executive Departments, upon any subject relating to the Duties of their respective Offices. In short, the secretaries and their departments are the administrative arm of the president.
