Answer:
<em><u>The answer is</u></em>: <u>The Legislative branch.</u>
Explanation:
The United States Constitution mentions only three branches of government: legislative, executive and judicial, articles I, II and III. Agencies are not mentioned in the Constitution, although federal agencies are sometimes referred to as "the fourth branch of government."
<u>The Supreme Court has recognized the legitimacy of federal administrative agencies</u>: Government, state or federal units, which have specialized experience and authority in some area of the economy, to make rules that have the same binding effect as statutes by Congress.
<u>Administrative agencies have the responsibility</u> to carry out a specific task or achieve a goal or set of goals. They must not remain, in acting because they have been granted legislative powers.
<em><u>The answer is</u></em>: <u>The Legislative branch.</u>
