Correct option is B
The correct answer is: (b) Mehrgarh
Explanation:
The evidence of the earliest cotton cultivation in the Indus Valley has been found at Mehrgarh, an important site of the Neolithic period located in modern-day Balochistan, Pakistan.
Excavations at Mehrgarh have revealed cotton seeds and textile fragments, indicating that cotton cultivation dates back to around 6000 BCE in this region, making it one of the earliest known instances of cotton farming in the world.
Information Booster:
Mehrgarh is one of the earliest known agricultural communities in the Indus Valley region. It predates the urban phase of the Indus Valley Civilization, and the evidence of cotton farming is one of its significant contributions to early agricultural practices.
Kalibangan and Harappa have also provided valuable information about the Indus Valley Civilization, but the earliest cotton cultivation evidence is specifically found in Mehrgarh.
