Explanation:

The description "Civilization that developed astrological calendars, grew crops on chinampas, and built pyramids in the jungle" matches the Aztecs. Chinampas (floating gardens) and jungle - built pyramids are key features of the Aztec civilization. The Incas were in the Andes (not jungle - based), the Olmecs are earlier and don't match this specific set of features, and the other options (Mercantilism, Capitalism, Pizarro, Cortes) are not civilizations with these traits.

Answer:

Aztecs
