← HistoryWhich environmental outcome accelerates decay when moisture enters spaces within Mughal pietra dura inlay?
A)Enhanced structural compressive strength
B)Widespread freeze-thaw delamination✓
C)Decreased material thermal expansion
D)Elevated resonant vibration frequency
💡 Explanation
Freeze-thaw cycles induce cracking because the volumetric change of water causes expansive stress exceeding the stone's tensile strength; therefore, widespread freeze-thaw delamination appears rather than other failure mechanisms absent penetrating moisture levels and sub-zero temperature conditions.
