Q. Which of the following rivers was known as “Drishdvati” in Vedic Era?
Answer: Ghagghar
Notes: In the Vedic era, the river Ghaggar-Hakra, which flowed through parts of present-day Rajasthan, Haryana, and Punjab in India, and Cholistan in Pakistan, was known as "Drishdvati" or "Drishadvati." The Ghaggar-Hakra river system was an important river during the Vedic period and is mentioned in ancient Hindu texts such as the Rig Veda, Mahabharata, and Puranas. It was one of the major rivers along which the early Vedic people settled and established their civilization. However, the Ghaggar-Hakra river system lost its prominence over time due to a number of factors, including tectonic activity and climate change. The river gradually dried up, leaving behind a dry channel that can still be seen today.
