Which disadvantage complicated 'pietra dura' inlay within massive Mughal structures?

A)Differential thermal expansion cracking risk
B)Inhomogeneous pigment suspension settling effects
C)Variable crystalline lattice stress corrosion
D)Anisotropic sonic resonance amplification cracking

💡 Explanation

Thermal stress induced cracking became critical because 'pietra dura' used diverse materials with varying thermal expansion coefficients; therefore expansion mismatches caused interface cracks, rather than pigment separation because settling and uniformity were already controlled at manufacture.
