Final answer:
The city founded by Menes to expedite unification was Memphis, and the largest city in Egypt at that time was Thebes, making the correct answer c) Memphis, Thebes.
Step-by-step explanation:
To expedite unification, Menes founded the city of Memphis. Egypt's largest city at the time was Thebes, with a population of about 10,000. Therefore, the correct answer is c) Memphis, Thebes.
Memphis was the ancient capital of Aneb-Hetch, the first nome (administrative division) of Lower Egypt. Its ruins are located near the town of Mit Rahina. Menes is traditionally considered the first Pharaoh of a unified Egypt and founder of Memphis, which he established as the capital. Thebes, meanwhile, was an Upper Egypt city located on the east bank of the Nile and came to be the most venerated city of Egypt. Eventually, Thebes would become the capital in the Middle and New Kingdoms and reach notable prominence.
