Answer:
The correct answer is D: the Maya
Explanation:
Although the first zero was found in Mesopotamia, the Mayans invented it separately from the Mesopotamian civilization in approximately 4 A.D.
They wrote zero as a shell-shaped number and used it in their Long Count Calendar as a place-holder.
For the Mayans, zero was the base for correct counting, so the first day of the month was zero, the second day was one, etc.
