A. Throughout history, the most fertile areas with abundant arable land and freshwater supplies served as hearths for the development of civilizations.

Explanation:

The early cultural hearths around the world can be found near the lands that were productive for the development of man and his civilization. Some of these areas are Nile river valley, Indus river valley, Wei-Huang Valley, Ganges river, Mesopotamia and Mesoamerica. All these heartlands around the globe flourished due to the presence of rich environments in terms of rich soil types, for the domestication of crops as they were mostly seen along the river and lakes beds. Thus there has been a diffusion of culture along with these places and domesticating animals also took place due to the same feature like Christianity in fertile crescent and Islam in Saudi Arabia.
