Which one of the following pairs of primitive tribes and places of their inhabitation is not correctly matched ?

Option 4 is incorrect. The Buksa (Bhoksas) are known to inhabit parts of Pauri‑Garhwal and adjacent Tarai/Bhabar areas, supporting option 1. The Kol tribe is recorded from central India including Jabalpur, validating option 2. The Munda are a principal tribal group of the Chotanagpur plateau (Jharkhand and adjoining areas), so option 3 is correctly matched. By contrast, “Korba: Kodagu” is not a correct pairing — Korba refers to central Indian contexts (and Korba is also a Chhattisgarh district), whereas Kodagu (Coorg) in Karnataka has distinct southern tribes; thus the Korba–Kodagu pair is mismatched.
