Solution & Analysis
Answer: B
Concept
A 'True Arch' is constructed using wedge-shaped blocks (voussoirs) that transfer the load sideways, a technique that was not common in India before the Sultanate period.Explanation
The Tomb of Ghiyas-ud-din Balban (built c. 1287) in the Mehrauli Archaeological Park is recognized as the first extant structure in India where a true scientific arch was successfully built. Earlier attempts at arches (like in Iltutmish's tomb) were 'corbelled' (pseudo-arches made by overlapping flat stones).Logical Breakup
Logic 1: Balban's tomb represents the moment when local Indian masons mastered the Persian technique of the scientific arch.
Logic 2: While the Alai Darwaza (1311) features much more refined true arches, Balban's tomb is the earlier historical prototype.
