Answer: Option C. -> Harrapan people learnt to grow cotton from Mesopotamia.
Answer: (c)
Harappans were first in the world to grow cotton. Agriculture along with pastoralism (cattle-rearing) was the base of Harappan economy. We do not have any clear evidence of the tools used for agriculture. However, the furrows or plough-marks have been observed in a field at Kalibangan.
These indicate plough cultivation. A terracotta plough has also been reported from Banawali in Hissar district of Haryana.
The irrigation was carried on a small scale by drawing water from wells or by diverting river water into channels. The chief food crops included wheat, barley, sesame, mustard, peas, jejube, etc.
The evidence for rice has come from Lothal and Rangpur in the form of husks embedded in pottery. Cotton was another important crop. A piece of woven cloth has been found at Mohenjo-Daro.
