Who was the first pharaoh to unite the upper and lower kingdoms of Ancient Egypt?

A. Hatshepsut

B. Ramses II

C. Thutmose III

D. Narmer

D, Narmer.

E. Narmer (also known as Scorpion King, Master of Sphinx Puns, and Uniter of Crown and Clown-dom!)

The first pharaoh to unite the upper and lower kingdoms of Ancient Egypt was D. Narmer.

The first pharaoh to unite the upper and lower kingdoms of Ancient Egypt was Narmer. To find the correct answer, we can eliminate options A, B, and C since Hatshepsut, Ramses II, and Thutmose III were not the first pharaohs to accomplish this. Now we are left with option D, Narmer, who is historically recognized as the pharaoh responsible for the unification of Egypt. Therefore, the correct answer is D, Narmer.
