Final answer:
The Head of an Akkadian ruler is a bronze sculpture from Nineveh, Iraq, dating back to around 2250-2200 BCE. It was created using the hollow cast technique and represents an Akkadian ruler, not made of basalt and not from Persepolis.
Step-by-step explanation:
The artifact in question is the Head of an Akkadian ruler, specifically believed to be from around 2250-2200 BCE and found in Nineveh (modern Kuyunjik), Iraq. It is not made of basalt rock but rather is a bronze sculpture created via a hollow cast technique, possibly using the lost-wax method. This hollow cast technique was indeed used in Akkadian art, contrary to the claim in option (d). Additionally, the artifact is not from the city of Persepolis as mentioned in option (c) but from the Akkadian Empire, more specifically Nineveh. The Akkadian Empire was known for its naturalistic sculptures that depicted political and warfare subject matters, like the Head of an Akkadian ruler, which combines naturalistic and stylized elements.
