Correct option is C
Cylindrical stone drills, used for bead making and other craft activities, have been found at the Harappan sites of Chanhudaro, Harappa, Dholavira, and Mohenjodaro. These drills indicate advanced technological skills and craftsmanship in the Indus Valley Civilization. Kalibangan, while an important site, has not yielded evidence of these specific tools.
Information Booster:
The Harappan civilization was known for its sophisticated craftsmanship, especially in bead making, metallurgy, and pottery. Cylindrical stone drills were crucial in bead drilling, enabling the production of intricate ornaments and tools. The presence of these drills at multiple sites illustrates widespread technological knowledge across the civilization.
Additional Knowledge:
• Chanhudaro and Mohenjodaro were prominent craft and trade centers with specialized artisans.
• Dholavira is noted for its unique urban planning and water management systems but also had advanced craft technology.
• Kalibangan primarily reveals agricultural and settlement evidence but fewer craft tools like drills.
