- Statement A is true. Harappan craftsmen used a wide variety of materials for bead making, including precious metals like gold, copper, and semi- precious stones like carnelian, jasper, crystal, steatite, along with shell, ivory, and faience. - Statement B is true. Archaeologists identify craft production sites like bead-making workshops by finding clusters of tools, raw materials, unfinished objects, waste products, and finished goods. - Statement C is true. Chanhudaro is a prominent Harappan site specifically known for being a major centre for craft production, including bead making. Excavations there have yielded extensive evidence of bead production processes, tools, furnaces, and beads in different stages of manufacture. - Statement D is the statement that is not true or at least less accurate compared to the well-documented evidence from other sites like Chanhudaro. While Banawali did have evidence of bead making, the specific description of a 'structure' yielding beads in 'various stages' is most strongly associated with sites like Chanhudaro or Lothal, which are more famously known as bead-manufacturing hubs with clear workshop structures. Banawali is known for other finds like a ploughed field and a street pattern, but the description in D is not its most salient feature regarding bead-making compared to Chanhudaro.
