A riser is a ___ pipe that supplies a sprinkler system.

Explanation:
A riser is a vertical pipe that carries water from the building’s main supply up through the sprinkler system, feeding sprinklers on different floors. Its vertical orientation is what lets the water reach upper levels, with branch lines running off horizontally on each floor to individual sprinklers. A lateral or horizontal pipe would stay on a single floor, not move water between levels, and a distributor refers to the part that feeds multiple branches rather than the vertical feed itself.
