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

Option 1 is not correctly matched. Jhummar (Jhumar) is recorded as a folk dance of Haryana. Thali is identified as a folk dance of Himachal Pradesh. Mukna is the traditional form of wrestling from Manipur and is associated with Manipuri folk tradition [1]. By contrast, the Korku-associated dance (e.g., Chatkora) is primarily linked to the Korku tribe of Madhya Pradesh. Although some sources note Korku dance occurrences in both Madhya Pradesh and adjoining Maharashtra, the primary association is with Madhya Pradesh, so pairing Korku exclusively with Maharashtra is incorrect. Hence the mismatched pair is Korku: Maharashtra (Option 1).
