The correct answer is D. Both were made up of two cycles that were used together to create a larger 52-year cycle.
The Maya had the Tzolk’in (a 260-day cycle) and the Haab’ (a 365-day solar calendar), which combined to create a Calendar Round of 52 years. Similarly, the Inca civilization utilized various systems in their calendar, which also involved cycles to track time, although the specific structure can differ.
