Case II weather requires the lowest ceiling to be ________ and 5 sm visibility.

Case II weather ties a ceiling minimum to a specified visibility, so you must have at least a certain height above the ground to accompany the 5 statute miles of visibility. The smallest ceiling that still satisfies the 5-mile visibility requirement is 1,000 ft. If the ceiling were 800 ft, you would fail to meet the minimum ceiling even though visibility is still 5 miles, so that wouldn’t meet Case II criteria. A ceiling of 1,500 ft or 2,000 ft would also satisfy the visibility requirement, but they aren’t the lowest acceptable ceiling.
