Q1. Who was the last official ruler of the princely state of Bundi?
Explanation
Maharao Raja Bahadur Singh was the last official ruler associated with the princely state of Bundi before the princely order was absorbed into the new political structure after independence. Ram Singh and Raghubir Singh were earlier rulers in Bundi's line and do not fit the final-ruler position. Ishwari Singh is not the Bundi ruler identified by this last official status. The question is about the closing phase of the princely state, so Bahadur Singh is the name that matches the official key and the historical sequence.
