The correct option is (a).
Explanation
The Indus Valley Civilization is recognized as one of the earliest centers in the world for the cultivation of cotton and the production of textiles.
Statement 1 is Correct:
Archaeological evidence confirms the presence of textiles in the Harappan civilization. Actual pieces of cloth were found attached to the lid of a silver vase and some copper objects at Mohenjodaro. Additionally, archaeologists have discovered spindle whorls made of terracotta and faience, which were used to spin thread.
Statement 2 is Incorrect:
Cotton was cultivated in the subcontinent long before the arrival of the Aryans. Evidence suggests that cotton was probably grown at Mehrgarh as early as 7000 years ago. The Harappans were among the first people to cultivate cotton and use it for weaving cloth. The Greeks later referred to cotton as sindon, derived from the word Sindh.
Key Takeaway:
The Harappans were pioneers in cotton cultivation and weaving, with physical evidence of textiles discovered at Mohenjodaro dating back to the mature Harappan phase.
