Answer:
D. Indian princes' inability to decide on a format of government
Explanation:
The most difficult obstacle to overcome in the creation of an autonomous state after Indian independence was achieved is "Indian princes' inability to decide on a format of government."
This is evident in the case of the likes of Jammu and Kashmir, Hyderabad State, Junagarh, and Kalat who all had difficulties in accession of their state or territory to the other bigger British Raj territory who has gained independence.
This is because they were originally using a monarchy style of governance before independence and find it hard to determine a format of government to use after independence
