Answer:
D. Complex Drainage
Explanation:
The Chavín civilization receives its modern name from their most important surviving settlement, at Chavín de Huántar. The temple ruins at Chavín de Huántar include many common Chavín motifs, such as people, birds, cats, crocodiles, and serpents. The temple shows that the Chavín understood drainage. To prevent the temple from flooding during the highlands' rainy season, it was built with complex drains that kept the temple dry.
