Which statement correctly describes how UsdGeomSubsets can be used to organize geometry for specific material assignments or rendering attributes in…

UsdGeomSubset is a schema derived from UsdGeomCollection explicitly designed to partition the faces of a single UsdGeomMesh into disjoint or overlapping groups so that each subset can carry its own material binding or other per-subset attributes. This enables multiple materials on one mesh without duplicating geometry.

B. Visibility/purpose are authored on Imageable prims, not face subsets; Subsets do not affect those attributes.

C. Subsets are logical groupings; they do not force tessellation.

D. Subsets live beneath the mesh they partition, not at the stage root.
