Which of the following statement (s) is true of the Harappa site of Indus Valley Civilisation?

All of the above

Although Harappa was the first site to be discovered, it was badly destroyed by brick robbers. As early as 1875, Alexander Cunningham, the first Director-General of the Archaeological Survey of India (ASI), often called the father of Indian archaeology, noted that the amount of brick taken from the ancient site was enough to lay bricks for “about 100 miles” of the railway line between L ahore and Multan. Thus, many of the ancient structures at the site were damaged. In contrast, Mohenjodaro was far better preserved.
