Answer: (iii) It cannot store color or material information

STL represents a 3D surface as a collection of triangular facets. The standard STL format mainly describes geometry and surface normals. It does not natively carry rich information such as color, texture, or multiple material assignments.

This is a major limitation when a model requires multi-material or color-aware manufacturing.
