Explanation: The Indus Valley Civilization, one of the world's earliest urban civilizations, flourished in the northwestern regions of the Indian subcontinent between 3300 BCE and 1300 BCE. This civilization is known for its advanced urban planning, extensive trade networks, and sophisticated craftsmanship. While the primary sites of the Indus Valley Civilization are located in present-day Pakistan and western India, there are also significant archaeological sites in the state of Haryana, India.
In Haryana, the Indus Valley Civilization sites are primarily found in the Hisar district. Two of the most important sites in this district are Bhirrana and Kunal. Bhirrana, located in Fatehabad tehsil, is one of the oldest known Indus Valley sites, with evidence suggesting that it was occupied from around 7500 BCE to 1900 BCE. Kunal, situated in the Hisar tehsil, is another significant site that has yielded a wealth of artifacts and structural remains dating back to the Indus Valley period.
The discovery of these sites in the Hisar district has provided valuable insights into the lifestyle, trade, and urban planning of the Indus Valley people. Archaeological excavations have uncovered pottery, seals, beads, and other artifacts that reflect the advanced craftsmanship and trade connections of the civilization. The urban planning at these sites is also noteworthy, with evidence of well-organized streets, drainage systems, and residential areas.
It is important to note that while the Indus Valley Civilization sites are primarily associated with the Hisar district in Haryana, other districts in the state do not have similar archaeological evidence. Karnal, Rohtak, and Nuh, mentioned in the other options, do not have known Indus Valley Civilization sites. These districts are significant for other historical and cultural reasons, but they are not part of the Indus Valley Civilization's geographical spread.
In conclusion, the correct answer is Hisar, as it is the district in Haryana where the Indus Valley Civilization sites are located. The archaeological findings in this district provide crucial information about the ancient urban civilization and its impact on the region. Understanding the geographical distribution of the Indus Valley Civilization sites is essential for comprehending the historical and cultural significance of this ancient civilization in the context of Haryana and the broader Indian subcontinent.
