Correct Answer : Harappan cemetery
The excavations in Sinauli were conducted by Archaeological Survey of India (ASI) in 2005-06 and in mid-2018. The remains found in 2005-06 season, the "Sanauli cemetery", belong to the Late Bronze Age, and were ascribed by excavation director Sharma to the Harappan Civilisation, though a Late Harappan Phase or post-Harappan identification is more likely.
Major findings from 2018 trial excavations are ascribed to the Ochre Coloured Pottery culture (OCP)/Copper Hoard Culture, which was contemporaneous with the Late Harappan culture.
