What is the primary function of the end line in Ultimate Frisbee?

• A. It marks the boundary at the end of the field.
• B. It marks the boundary along the sideline.
• C. It marks the center line for starting positions.
• D. It marks the boundary at the end of the field; crossing it can result in a turnover if the disc is out of bounds.

Answer: (D)

The end line defines the boundary at the far ends of the field. It’s the line you can’t cross to keep the disc in play. If the disc completely crosses that line, it’s out of bounds, and possession changes to the other team as a turnover, taken at the spot where the disc crossed the line. Remember, touching or landing on the end line itself is still in bounds, but going past it is not. This is why the option that states the end line marks the boundary at the end of the field and crossing it can result in a turnover when the disc is out of bounds is the best choice. It accurately describes both the boundary role and the consequence of crossing it. The sideline is a different boundary, and the center line is used for starting placements, not the end-line boundary function.
