Answer:
The correct answer is letter D. What completes this sequence of events is: the President must act on the bill.
Step-by-step explanation:
After the U.S Senate passes the spending bill it is ready to go to the President. When the bill reaches him, he has the choice of sign and pass the bill, and then the bill becomes a law. Or the President can also veto the bill, when he refuses to sign it. When that happens the bill is sent back with the reasons why it was denied, if the Senate still thinks the bill should be a law, they can do another vote on it.
If a bill has passed all the steps it becomes a law and is enforced by the government.
