Final answer:
The Baise and Chaubise states originated from Medieval Nepal, where they formed after the disintegration of previous kingdoms and were later unified by the Gorkha Kingdom.
Step-by-step explanation:
The origin of the Baise and Chaubise states is associated with A. Medieval Nepal. The Baise (twenty-two) and Chaubise (twenty-four) principalities were small kingdoms in the Gandaki region of Nepal during the medieval period. They emerged after the disintegration of the larger regional kingdoms that were present before, ultimately becoming part of the unification of Nepal. This process of consolidation was largely accomplished by the King Prithvi Narayan Shah and the Gorkha Kingdom in the 18th century.
