In stair construction, "rise and run" specifically refers to the dimensions of individual steps. The rise is defined as the vertical height of each individual step, which determines how far up each step elevates a person as they use the stairs. Conversely, the run is defined as the horizontal depth of each step, which dictates how far forward the step extends. This concept is critical for ensuring that stairs are comfortable and safe to use, as proper measurements contribute to a gradual incline and minimize the risk of tripping or falling.

The correct understanding of rise and run is foundational in stair design, ensuring that stairs conform to safety standards and accessibility guidelines, making option C the accurate definition.
