Which statement correctly describes a riser in a piping system?

Explanation:
A riser is the vertical pipe that carries the water supply upward to the floors above. In a building, the main or lower-level supply is distributed upward through these vertical runs, and from the riser, branches on each floor feed the fixtures with horizontal piping. That’s why describing it as carrying water supply vertically to upper floors fits its function best. It isn’t a valve or a pump, and the horizontal delivery to fixtures is handled by branch or distribution piping off the vertical riser.
