The correct option is C Barley
Cultivation of the cereals began about 10,000 years ago as a major part of the shift from hunting and gathering to plant and animal husbandry, a transition that stimulated rapid social and cultural evolution. Emmer wheat, einkorn wheat, and barley were three of the so-called Neolithic founder crops in the development of agriculture. Domestication of poaceous cereal crops such as maize (corn), wheat, rice, barley, and millet lies at the foundation of sedentary living and civilization around the world, and the Poaceae still constitute the most economically important plant family in modern times, providing forage, building materials (bamboo, thatch) and fuel (ethanol), as well as food.
