Which key outcome resulted from optimizing the stone finish of Inca masonry?

💡 Explanation

The Incas aimed to avoid mortar in stonework; optimized surface finishing resulted in tightly interlocking stones, minimizing stress concentrations during earthquakes due to friction damping, because the stones could shift rather than fracture. Minimizing seismic damage prevailed; therefore A is right rather than alternatives that provided solely cosmetic benefits.
