Correct Answer: (B) Mahadaha

Explanation:

Excavations at Mahadaha, a Mesolithic site in Uttar Pradesh, India, have yielded evidence of bone ornaments. This site is known for its rich collection of artifacts, including bone tools, beads, and pendants, indicating the use of bone for both practical and decorative purposes during the Mesolithic period.

While other options might have archaeological finds, here’s a breakdown of why they are less likely:

• (A) Sarai Nahar Rai: This site is also known for Mesolithic artifacts, but evidence of bone ornaments specifically is less documented compared to Mahadaha.
• (C) Lekhahia: This site is associated with the later Harappan period (Indus Valley Civilization) and is not known for Mesolithic finds.
• (D) Chopani Mando: Primarily associated with the Indus Valley Civilization, similar to Lekhahia, this site falls outside the Mesolithic timeframe.
