Final answer:
If the president does not sign a bill within ten days while Congress is in session, it automatically becomes law unless Congress adjourns before the ten days are up. Option 1 is the correct answer among the given option.
Step-by-step explanation:
According to Section 7 Clause 2 of the United States Constitution, if the president does not sign a bill within ten days of receiving it while Congress is in session, the bill automatically becomes law, unless Congress adjourns before the ten days are up. In that case, it is considered a "pocket veto" and the bill does not become law.
The president also has the option to veto a bill by sending it back to Congress with objections. If Congress can muster a two-thirds majority vote in both houses, they can override the veto and the bill becomes law.
So, Option 1 is the correct answer among the given option.
