Which aesthetic degradation results when moisture diffuses through underlying brickwork via capillary action within Mughal-era pietra dura inlay?

💡 Explanation

Efflorescence appears because soluble salts migrate to the surface, then evaporate and deposit salt crystals. This capillary action is a specific type of mass transport; therefore, efflorescence damages the aesthetics rather than oxidation, chemical change, or simple discoloring of its components.
