Which risk increases for pietra dura inlay when significant diurnal temperature variation affects the Taj Mahal?

A)Differential thermal expansion occurs
B)Oxidation rate accelerates significantly
C)Material dissolution process accelerates
D)Microbial contamination increases rapidly

💡 Explanation

Delamination risk increases because differential thermal expansion occurs between the marble and the inlaid stones. The linear thermal expansion coefficients differ; therefore, internal stresses cause loss of adhesion rather than uniform change.
