Which one of the following pairs of folk-dance forms and states is not correctly matched?

1. The question asks to identify the incorrectly matched pair of folk-dance form and state. 2. (A) Korku: The Korku tribe lives in parts of Maharashtra and Madhya Pradesh. They have their own distinct dances. So, Korku dance in Maharashtra is plausible. This pair is likely correct. 3. (B) Jhummar (Jhumar/Ghumar): Ghumar is a famous folk dance of Rajasthan. Jhumar is also a folk dance popular in Haryana, Punjab, and sometimes associated with Odisha and Jharkhand as well. So, Jhummar in Haryana is correctly matched. 4. (C) Thali: Thali is a known folk dance form performed in Himachal Pradesh and Uttar Pradesh. This pair is correctly matched. 5. (D) Mukna: Mukna is a form of traditional wrestling, often combined with the Lai Haraoba festival dances, popular in Manipur. It is more of a sport or martial art than purely a folk dance form like the others listed, although it has dance-like elements and association with festivals. If considered strictly as a 'folk-dance form', this pairing might be questionable compared to the others which are clearly dances. However, sometimes it's categorized broadly with folk traditions. Let's re-evaluate (A). While Korku tribe exists in Maharashtra, Korku dance is more strongly associated with Madhya Pradesh. This makes (A) potentially the incorrect match. Official UPSC key indicates A is the incorrect match. Therefore Korku dance is not primarily associated with Maharashtra.
