The correct answer is letter C.
The Mayans are known for their use of a Calendar to plan and organize activities. The Mayan Calendar is separated in "<em>the Long Count</em>", "<em>the Tzolkin</em>" and <em>"the Haab</em>". Each one corresponds to a cycle, which means that there's a certain number of days to occur before the other one begins.
The Incas, on the other hand, would use Divination to seek knowledge of the future. This practice would be used to diagnose illnesses, investigate crimes, decide the sacrifices that were to be made to gods, inform people of social events, and others.
Incas would consult oracles, observe the movements of a spider and the coca leaves and drink ayahuasca (which is an hallucinogen tea) in order to have the answers they were looking for.
