Final answer:
Early civilizations flourished along river valleys mainly due to the fertile soil and water provided by rivers. The fertile soil was ideal for agriculture, and the availability of water allowed for irrigation and transportation.
Step-by-step explanation:
Early civilizations, such as the Egyptians and the Sumerians, often flourished along river valleys primarily due to the immense agricultural benefits provided by these areas.
The statement c) Rivers provided fertile soil and water for agriculture is accurate. Rivers, particularly during annual floods, deposit layers of rich, fertile silt that create excellent soil for farming.
In addition, the water from the rivers served not only as a source of irrigation for crops but also as a means of transportation for goods and people. Therefore, these river valleys became ideal locations for those early civilizations to grow and thrive.
