The distinction between a standpipe system and a sprinkler system primarily lies in their intended function and method of operation. Standpipe systems are designed to provide a readily accessible supply of water for firefighting, allowing firefighters to connect hoses and draw water directly from a designated piping network throughout a building. They are typically found in buildings where manual firefighting needs to be supported, particularly in high-rise structures or large commercial spaces.

On the other hand, sprinkler systems are automatic water suppression devices that activate in response to heat from a fire. When a fire occurs, specific sprinklers will activate based on temperature thresholds, discharging water directly onto the fire to suppress or extinguish it, thus providing an active means of fire control without the need for firefighter intervention.

This fundamental difference in functionality is what primarily differentiates the two systems, hence making the second choice the correct response.
