Answer:
The best answer is D. The budget is ready for the start of the new fiscal year on October 1.
The federal government's fiscal year runs from October 1 to September 30 of the following year. Congress and the president work to pass a new budget and have it enacted by the end of September so that government agencies and programs have the necessary funding to operate at the start of the new fiscalyear on October 1. This allows for a smooth transition from one fiscal year to the next and ensures that the government can continue to provide services and carry out its functions without interruption.
