From the twenty-fifth century BCE, pharaohs' tombs were located inside grand pyramids. The pyramids served as giant grave markers; however, they also served as treasure markers for grave robbers. These wicked people would strip the tomb bare of valuables. Then they would sell the stolen items for a large amount of money. Stealing from the dead was bad enough, but for the ancient egyptians, the act also threatened the pharaoh's afterlife.
The answer is ( B grave robbers were unconcerned about the pharaoh's afterlife), tell me why B is correct?
