From which of the following archaeological sites has the skeleton of Homo…

Fossil evidence of early human (hominin) evolution in India is extremely rare; a site is credited with a hominin skeletal find only when actual cranial or skeletal remains, not merely stone tools or rock art, have been excavated and scientifically dated there.

In 1982, a fossilised hominin skullcap (calvarium) was excavated from river-terrace deposits at Hathnora, on the banks of the Narmada river in the Narmada Valley, Madhya Pradesh. Its discoverer classified it as Homo erectus — the name by which the "Narmada Man" fossil is still commonly described in Indian exam literature — though its precise species-level attribution (some later studies have proposed archaic Homo sapiens or Homo heidelbergensis affinities) remains debated among palaeoanthropologists. It is nonetheless the only Homo erectus-attributed skeletal find reported from the Indian subcontinent, which is why Hathnora is the site referred to in the question.

• Amarkantak, in Madhya Pradesh, is the origin point of the Narmada and Son rivers and is known as a pilgrimage and hill-station town; no hominin skeletal fossil has been recovered here.

• Bhimbetka, in Madhya Pradesh, is a UNESCO World Heritage rock-shelter complex known for its prehistoric rock paintings and stone-tool assemblages spanning the Palaeolithic to Mesolithic periods, but no Homo erectus skeleton has been excavated there.

• Damdama, in Uttar Pradesh, is a Mesolithic-period site known for excavated human burial skeletons, which belong to anatomically modern Homo sapiens of a much later era, not Homo erectus.

Hence, Hathnora is the archaeological site conventionally identified as the source of the Homo erectus ("Narmada Man") skeletal find.
