The correct answer is option C. From the complex building structures like the ziggurat it can be inferred that Mesopotamian societies, such as the Sumerian, used advanced technologies in architectural construction.
The Ziggurat is a type of huge stone structure which has the form of a terraced compound of successive levels. They represent the most remarkable and famous Sumerian buildings, where the advanced materials and techniques applied by this ancient civilization are put in manifest. Some of the most famous ziggurats are the Great Ziggurat of Ur, the Ziggurat of Aqar Quf and the Etemenanki in Babylon among others now destroyed.
