The question asks about the first site where the Indus Valley Civilization was discovered. The Indus Valley Civilization is one of the world's earliest urban civilizations. It flourished in the northwestern regions of South Asia, particularly in present-day Pakistan and northwest India. The discovery of this civilization was a significant archaeological find.
The correct answer is Harappa. Harappa was the first site to be excavated in 1920, marking the discovery of the Indus Valley Civilization. This site, located in present-day Pakistan, provided critical insights into the life, culture, and architecture of the civilization. It was from Harappa that the civilization got its alternative name, the Harappan Civilization.
The first site where the Indus Valley Civilization (IVC) was discovered is Harappa (in present-day Punjab, Pakistan).
