B Correct answer
Explanation

The Nile River Valley has supported dense populations for thousands of years due to fertile soil from annual flooding, reliable water supply, and the historical development of civilizations along its banks. The Niger, Congo, and Zambezi river valleys, while populous, do not match the Nile's historical population density.
