Explanations:The Indus Valley Civilisation, also known as the Harappan Civilisation, was one of the earliest urban civilisations in the world, flourishing between approximately 2600 and 1900 BCE. This civilisation was primarily located in the northwestern regions of the Indian subcontinent, encompassing parts of present-day Pakistan and India. Among the numerous sites associated with this civilisation, Lothal stands out as a significant urban centre located in present-day Gujarat, India.
Lothal is particularly notable for its advanced urban planning and sophisticated infrastructure. The site includes a well-planned city layout with a grid of streets, a drainage system, and a dockyard that suggests it was a major port city. The dockyard at Lothal is considered one of the earliest known in the world, indicating the civilisation's advanced understanding of maritime trade and navigation.
The discovery of Lothal and other sites in Gujarat has provided valuable insights into the economic, social, and technological aspects of the Indus Valley Civilisation. The city's strategic location on the Gulf of Khambhat (Cambay) made it an important hub for trade, connecting the region to other parts of the civilisation and possibly to distant lands through maritime routes.
Understanding the geographical distribution of Indus Valley Civilisation sites is crucial for comprehending the extent and complexity of this ancient civilisation. While many sites are located in present-day Pakistan, such as Harappa and Mohenjo-Daro, Lothal represents the presence of this civilisation in the western part of India, specifically in Gujarat. This distribution highlights the vast expanse of the civilisation and its influence across diverse regions.
It is important to note that other options like Harappa, Rangpur, and Lahore are not associated with the Indus Valley Civilisation sites in Gujarat. Harappa is a significant site in Pakistan, Rangpur is a city in Bangladesh with no connection to the Indus Valley Civilisation, and Lahore is a major city in Pakistan that is not part of the ancient civilisation's sites in Gujarat.
Thus, Lothal is the correct answer as it is the main city of the Indus Valley Civilisation that is presently a part of Gujarat, reflecting the civilisation's presence and influence in this region.
