Which statement best describes an OB disc?

• A. A disc that lands outside the boundary lines or is caught outside them.
• B. A disc that lands in the end zone.
• C. A disc that is intercepted.
• D. A disc that bounces on the sideline.

Answer: (A)

An out-of-bounds disc is one that is no longer in play because it left the playing area. The boundary lines define in-bounds, and if the disc lands outside those lines or is touched/caught outside them, it’s considered out of bounds. When this happens, play stops and possession is awarded to the defense at the spot where the disc crossed the boundary. This is why the statement describing an OB disc as landing outside the boundary lines or being caught outside them is the best match.

The other scenarios describe different outcomes: landing in the end zone is a score, an interception is a turnover but not necessarily about being out of bounds, and a disc bouncing on the sideline isn’t automatically out of bounds—the line itself is in play, and the disc’s final resting spot determines OB status.
