Which of the following pairs is NOT correctly matched? State Ruler

1. A

   Devgiri Shankar Dev

   Devagiri (Daulatabad) of the Yadavas is associated with Ramachandra and then Shankaradeva; Shankar Dev as a Devagiri ruler is treated as a correct pair in this list. This option is not the unmatched one.

2. B

   Warangal Ramchandra Dev

   Warangal was the Kakatiya capital; its last great ruler was Prataparudra, not Ramachandra Dev. Ramachandra Dev belongs to Devagiri. This mismatched pair is the official key.

3. C

   Hoysal Veer Ballal

   The Hoysalas are correctly linked with Vira Ballala (several kings of that name). This option is not the key.

4. D

   Madura Veer Pandya

   Madurai’s later Pandya line includes Vira Pandya as a recognised royal name. This option is not the unmatched pair as keyed.

Summary. Official key is (b) Warangal–Ramchandra Dev. Alauddin Khalji and Malik Kafur’s Deccan raids struck Devagiri’s Ramachandra and Warangal’s Prataparudra as separate kings. Hoysala Vira Ballala and Madurai Vira Pandya stand as given. Only Warangal is wrongly given Ramachandra.
