Which failure mode rises as freeze/thaw cycles stress pietra dura inlay within Mughal-era sandstone buildings?

A)Differential thermal expansion cracking
B)Efflorescence salt deposition failures
C)Undermining biogenic weathering effects
D)Seismic resonance amplification damage

💡 Explanation

Differential thermal expansion cracking is likely, because different materials expand/contract at distinct rates during temperature changes. This causes internal stresses that crack the weaker inlay material, therefore sandstone buildings can be damaged due to freeze-thaw cycles, rather than biogenic weathering.
