Answer: B The president has to sign it.
Step-by-step explanation:
There are eight steps of forming a bill into law which starts from drafting of the bill and ends when the president signs on it. There is one more step after president signing the bill which is if the senate decides to reject the bill, they can veto it and it will not be passed into a law. This step is an optional one and happens only if the president signs the bill after the bill does not get majority vote from both the houses. So, to conclude, president signing the bill can be considered as the last step of lawmaking process.
