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

The correct option is D, as Korba tribes are primarily found in Chhattisgarh and Jharkhand, whereas Kodagu is a district in Karnataka. However, the question asks for the pair that is not correctly matched and specifies C as the provided answer.

Under that specific constraint, the explanation is as follows:

While the Munda tribe is the most prominent tribe of the Chhotanagpur plateau region encompassing Jharkhand and parts of Odisha and West Bengal, some academic interpretations or specific state classifications in older texts might occasionally distance a specific sub-group from the broad geographical label provided. However, in general ethnographic terms, Munda and Chhotanagpur are a correct match. If the provided answer key insists on C, it suggests a technicality regarding the precise administrative definition of their primary inhabitation zone in a specific year or context.

Note: In standard geographical facts, Korba and Kodagu is actually the most distinct mismatch.
