A GIS analyst has a buildings feature class.

Attribute-driven symbology allows different fields to control different aspects of visualization. In this case, one field (building type) can control color or symbol category, while another field (building height) controls the 3D extrusion. Attribute-driven symbology is designed specifically for this type of multi-attribute control.

Bivariate colors (Option B) map two numeric fields into a color grid but do not control extrusion.

Dictionary symbology (Option C) applies rule-based symbology often used for military or complex symbols, not 3D extrusion.

Therefore, the correct answer is A.
