Dear student
In 1920, Rai Bahadur Daya Ram Sahni conducted the first detailed excavations at Harappa. In Punjab, Pakistan, about 24 km west of Sahiwal, Harappa is an archaeological site. The site is named after a modern village situated along the old Ravi River course that now runs 8 km to the north. Less than 1 km from the ancient site is the present village of Harappa. The Indus River Valley Civilization, also known as the Harappan Civilization has established the first reliable system of uniform weights and measures. Harappans made sculpture, seals, pottery, and jewellery from materials such as terracotta, copper, and stone. The Harappan culture was characterized by its town planning system. Harappa and Mohenjo-Daro both had their own citadel or acropolis, probably populated by ruling class members. Enough food grains were developed by the Harappan villages, mostly situated near the flood plains. Most of the Harappan sites are situated in semi-arid fields, where agricultural irrigation was possibly appropriate. Traces of canals were discovered at Shortughai's Harappan site in Afghanistan, but not in Punjab or Sindh. While agriculture was practised by the Harappans, animals were also reared on a large scale.
Therefore, the correct answer is A
