Answer:
c. the budget for every presidential action has to be approved in advance
Step-by-step explanation:
As an effort to balance the power between government branches, the law allowed the Government to veto the budget proposal made by the congress.
This allow the presidents to walk around the congress' restriction unless the congress able to gather enough members (more than 2/3) to override the veto. So technically, the budget does not need to be approved in advance.
