Which structural advantage results from Inca ashlar masonry techniques?

A)Earthquake resilience due to interlock
B)Improved insulation against temperature
C)Increased resistance against chemical weathering
D)Reduced material use; hollow structures

💡 Explanation

The precise shaping and fitting of stones creates strong interlocking, thus maximizing frictional resistance to lateral displacement, a process called mechanical interlocking. Therefore, Inca walls withstand seismic forces, rather than collapsing under stress such as with stacked block masonry.
