Which outcome occurred increasingly in Mughal monuments when subsurface water-table levels dramatically rose near 'pietra dura'?

💡 Explanation

Rising groundwater dissolved subsurface salts and then capillary action drew this saline water into the porous stone structures. The resulting efflorescence created crystallized salt deposits on 'pietra dura' surfaces because of evaporative salt concentration, therefore widespread damage, rather than alternatives from seismic events or structural weaknesses occurred.
