Which describes the pocket veto? a veto resulting from the president's inaction a veto of a single item in an appropriations bill a veto that returns the bill to the house where it was introduced a veto that was declared unconstitutional in 1998

The pocket veto is the one resulting from the President's inaction.  

It´s a legislative maneuver that allows a president to refuse a law by taking no action (instead of affirmatively vetoing it).

It occurs when the president does not sign the bill and cannot return the bill to Congress within a 10-day period because Congress is adjourned and unable to override a veto.
