Q. At which among the following sites, first evidence of cotton fibres has been found?
Answer: Mehrgarh
Notes: Mehrgarh is associated with the earliest known archaeological evidence of cotton fibres in the Old World. Mineralised cotton fibres were recovered from a copper bead found at the Neolithic site, showing that cotton was already being used there in very early times. This discovery is important for the history of textiles and agriculture in South Asia, and it remains one of the key references for the early use of cotton in prehistoric times.
