Solution & Analysis

Answer: A

Concept 'Surkhi' is a building material made from ground burnt bricks or clay, used as a hydraulic mortar or concrete substitute to provide strength to structures.

Explanation Excavations at Mathura, a primary Kushan capital, reveal five distinct levels of occupation. The levels associated with the Kushan period show significant use of Surkhi in the construction of brick stupas, platforms, and shrines, marking its systematic introduction into Indian masonry.

Logical Breakup
Logic 1: While brick-making was known since Harappan times, the specific use of ground brick-dust (Surkhi) as a strengthening agent in mortar became prevalent during the Kushan era.
Logic 2: This material allowed for more durable brick structures, bridging the gap between early timber-influenced designs and the sophisticated stone architecture of the Guptas.
