The correct statement that explains what happens when the president issues a pocket veto is:
Congress will adjourn within 10 days of the president receiving the bill. If the president does not sign the bill, the bill does not become a law because Congress will not have an opportunity to override the veto.
In a pocket veto, if Congress adjourns within the 10 days after the bill is presented to the president and the president does not sign it, the bill fails to become law without a formal veto.
