Which mechanism causes increased efflorescence within Mughal garden fountains, resulting in damage?

💡 Explanation

Salt accumulates because saline groundwater rises through porous sandstone via capillary action, therefore dissolved salts crystallize on surfaces, damaging the pietra dura; rather than water expansion or plants, saline water concentration causes salt buildup.
