The correct option is Kalibangan.
Explanation
The Indus Valley Civilization (Bronze Age) is renowned for its metallurgical skills, particularly the Cire Perdue (lost-wax) technique used for casting bronze and copper sculptures. While human figures like the 'Dancing Girl' are iconic, animal figures also demonstrate high artistic merit and anatomical realism.
Detailed Analysis
- Kalibangan: This site yielded a significant copper/bronze figure of a bull. The artifact is celebrated for its realistic rendering, dynamic posture, and mass, which art historians describe as being comparable in quality to the human figures found at Harappa and Mohenjo-Daro.
- Lothal: While Lothal was an industrial center that produced copper objects (such as a copper dog and bird), it is not the site associated with the specific bronze bull described in the question.
- Dholavira: This site is primarily famous for its unique water management system, stone architecture, and the large signboard inscription, rather than bronze animal figurines.
- Rakhigarhi: As the largest Harappan site, it has yielded numerous terracotta figurines and jewelry, but it is not the specific source of the bronze bull in question.
Key Takeaway: The realistic copper/bronze bull is a hallmark artifact of Kalibangan, distinguishing it from the bronze 'Dancing Girl' of Mohenjo-Daro and the stone torso of Harappa.
