← HistoryWhich outcome regarding structural integrity results when seasonal temperature cycling impacts the delicate `pietra dura` inlay within Mughal-era sandstone structures?
A)Increased susceptibility to compressive spalling
B)Progressive degradation via frost wedging✓
C)Decreased axial load bearing capacity
D)Enhanced resistance to seismic stress
💡 Explanation
Frost wedging occurs in regions experiencing freeze-thaw cycles, because water penetrates pores in the `pietra dura` and expands upon freezing, therefore exerting pressure leading to cracking and eventual disintegration, rather than uniform compressive stress.
