C). Agricultural

Explanation:

AGRICULTURAL societies relied on permanent tools for survival, and expanded due to innovations such as crop rotation and fertilizer.

An agricultural society, also known as an agrarian society, is a society that constructs social order around a reliance upon farming. More than half the people living in that society make their living by farming.

People in an agricultural society generally lead a more settled lifestyle than those in nomadic hunter-gatherer or semi-nomadic pastoral societies because they live permanently near the land that is farmed. Agricultural settlements tend to develop in areas of convenience near bodies of water, which is used for both crops and transportation, or along trade routes. Not everyone in an agricultural society is a farmer. Some people make a living trading or making and selling goods such as tools used for farming.
