Final answer:
The Inca Empire faced geographic challenges such as rugged terrain and steep mountains but adapted by building irrigation systems and terraces to manage these difficulties. Option c) is correct.
Step-by-step explanation:
The Inca Empire faced significant challenges due to its geographic context, most notably rugged terrain and steep mountains. The Inca were skilled at overcoming their environment and made numerous adaptations to thrive within it. They developed extensive irrigation systems and agricultural terraces, which not only supplied water but also prevented soil erosion and allowed for the cultivation of various crops at different elevations.
Although the Inca had the means to mitigate some of the difficulties presented by their environment, the challenges of their geographic context included managing steep mountains that complicated travel, communication, and the transportation of goods across the empire.
