Final answer:
The architecture of the Incas at Machu Picchu was characterized by sophisticated stone masonry, fitting the mountainous terrain with well-planned, sectional layout. The correct answer is option (b).
Explanation:
The architecture of the Incas at Machu Picchu predominantly exemplifies sophisticated stone masonry rather than wooden structures. The Incas were exceptionally skilled stone masons, constructing their buildings with tightly fitted stone blocks that required no mortar.
An evidence of this is the intricate stone walls that still stand in Machu Picchu. Furthermore, the layout of the architecture at Machu Picchu was not circular. Instead, it was well-planned and sectional, designed to fit the mountainous terrain.
