Which of the following listed rulers was the first to unify Egypt?

The unification of Egypt is attributed to Narmer, who is often considered the first pharaoh of a unified Egypt around 3100 BCE. His achievements marked the end of a period of fragmentation and the beginning of the Early Dynastic Period. Narmer is traditionally depicted in ancient Egyptian artifacts, most notably the Narmer Palette, which showcases his military conquests and the merging of Upper and Lower Egypt, symbolized by his wearing both crowns.

Naram-Sin, Hammurabi, and Ur-Nammu were significant rulers in their own right but belong to different cultures and time periods. Naram-Sin was a ruler of the Akkadian Empire and is known for his conquests and establishing his divine authority. Hammurabi is famous for his law code and ruled Babylon, while Ur-Nammu was a Sumerian king known for his legal reforms. Each of these rulers made impactful contributions to their societies, but none unified Egypt like Narmer did.
