C. An ancient rock quarry.

Explanation:

Pyramids are the structure whose outer surface are triangular in shape and converges from four sides to a single top. These Egyptian pyramids are one of the world's largest construction but the construction technique of these pyramids resulted in many hypotheses, out of which one hypotheses is that the huge stones (construction material of pyramids) were carved out from quarries which were then dragged to their positions. However, there are disagreement over the issue that how these huge block of stones are moved and placed to their current position. Archaeologists believe that these huge blocks of stone were moved by the slave labor.
