In Building Information Modeling (BIM), what name do we apply to rules that determine an objects geometry?

Parametric modeling is used to define geometry through Parameters and constraints that establish relationships between parts. In BIM, objects are created as families with adjustable dimensions and rules; changing a parameter automatically updates the geometry to maintain those relationships. This is exactly what “rules that determine an object’s geometry” refers to—geometry driven by parameters. The other terms describe data attached to objects or generic concepts, not the mechanism that generates and controls the shape itself.
