The statement that says Authorization Bills establish or modify federal agencies is true.
Answer: Option A
Step-by-step explanation:
The creation of any new Federal Agencies can only be done through the use of the Authorization Bill. The United States Congress has the power to create and authorise an agency to run for a specific cause.
Through authorisation and appropriation, an agency officially becomes a part of the government and becomes eligible to exercise powers given to it by the Congress.
