The correct answer is: B. Rakhigarhi
Rakhigarhi is an archaeological site in Hisar district, Haryana, India. It is one of the largest Harappan sites discovered so far, covering an area of over 350 hectares (865 acres). The site was first excavated in 1963 by B.B. Lal, and further excavations have been conducted by the Archaeological Survey of India (ASI) since 1997.
The site has yielded a rich variety of artifacts, including terracotta sculptures, pottery, beads, and seals. Two terracotta sculptures of Matra Devi have been found at the site. These sculptures are dated to the Mature Harappan period (2600-1900 BCE).
Matra Devi is a Hindu goddess who is worshipped as the mother goddess. She is often depicted as a nude woman with four arms, holding a child in one arm and a lotus flower in another. She is also sometimes depicted with a snake around her neck.
The terracotta sculptures of Matra Devi found at Rakhigarhi are significant because they provide evidence of the worship of this goddess in the Harappan civilization. The sculptures also suggest that the Harappans had a sophisticated understanding of art and religion.
The other options are incorrect because they are not archaeological sites in Haryana where terracotta sculptures of Matra Devi have been found.
