Is the movement which involves the concentration of the population in cities?

The movement of people resulting in the concentration of a population in cities is called urbanization. This is marked by more people occupying city, towns, or general urban areas as opposed to rural communities. Urbanization results in a progressive increase in city populations and a larger urban area.

The correct answer will be option-B.

Explanation:

Homo neanderthelensis or Neanderthals are the close relatives of the Homo sapiens or modern humans which became extinct around 10,000 years ago.

The Neanderthals and sapiens are the two related species of the same genus Homo but they showed distinct features like Neanderthals were muscular and shorter in height compared to the Homo sapiens. Recent fossils indicated that Neanderthals and Homo sapiens interbreed in some parts of the world as they were closely related to each other.

Thus, Option-B is the correct answer.
