C. The valleys had water access and fertile soil.

Explanation:

This is the main reason why many early farmers settled in river valleys. The main advantage that river valleys provided was the availability of water. This was particularly important at a time when irrigation was non-existent. Moreover, land that is located next to rivers tends to be more fertile. This made farming easier and allowed large communities to develop.
