Which of the following Indian language group matches correctly with its speech area?

North Dravidian - Odisha : Key Points This is the correct match. The North Dravidian languages, including languages like Kurukh and Malto, are primarily spoken in parts of eastern India, including areas in Odisha. This region has linguistic diversity that includes Dravidian languages, even though they are more commonly associated with southern India. Additional Information Dardic - Nicobar Islands : This option is incorrect. The Dardic languages are part of the Indo-Aryan language family and are primarily spoken in the northern regions of Pakistan and in Jammu and Kashmir in India, not in the Nicobar Islands. The Nicobar Islands, located in the Bay of Bengal, have their own indigenous languages unrelated to Dardic languages. Mon-Khmer - Assam : This option is incorrect. Mon-Khmer languages are a branch of the Austroasiatic language family. While some Austroasiatic languages, like Khasi and Munda languages, are spoken in India, the Mon-Khmer languages are predominantly found in Southeast Asia, not in Assam. Assam is predominantly home to Indo-Aryan and Tibeto-Burman languages. Munda - Jammu and Kashmir : This option is incorrect. Munda languages are part of the Austroasiatic language family, but they are primarily spoken in the central and eastern parts of India, such as in Jharkhand, Chhattisgarh, West Bengal, and Odisha, not in Jammu and Kashmir. Jammu and Kashmir are more associated with Dardic and Tibeto-Burman languages. In summary, the correct match is North Dravidian languages being spoken in Odisha, as it aligns with the geographical distribution of the Dravidian language family in India. The other options incorrectly match language families with regions where they are not primarily spoken.
