The correct answer is Rakhigarhi.

• The site of Rakhigarhi is one of the five known biggest townships of Harappan civilization on the Indian sub-continent.
• It is located in the Hisar district of Haryana state in India.
• The other four are
  • Harappa, Mohenjodaro, and Ganveriwala in Pakistan and Dholavira (Gujarat) in India.
• This site was excavated by Shri Amarendra Nath of the Archeological Survey of India.

• The archaeological excavations revealed a mature Harappan phase represented by a planned township having mud-brick as well as burnt-brick houses with a proper drainage system.
• Animal sacrificial pit lined with mud-brick and triangular and circular fire alters on the mud floor have also been excavated that signifies the ritual system of Harappans.
• Other antiquities included blades; terracotta and shell bangles; beads of semiprecious stones, terracotta, shell and copper objects; animal figurines, toy cart frame and wheel of terracotta; bone points; inscribed steatite seals and sealings.
• The excavations have yielded a few extended burials, which certainly belong to a very late stage, maybe the medieval times.
