Correct Answer: (b) Junagarh, Hyderabad, Jammu and Kashmir
Solution:Integration of most of the princely states happened in 1947. All Princely States merged into the Union of India in 1947 except Junagarh, Jammu & Kashmir, and Hyderabad. These three states were compelled to join the Union of India until the end of 1948. Sardar Patel, who took charge of the state department in 1947, tackled the situation with great statesmanship. Patel appealed to the patriotic and nationalist sentiments of the Princes and requested the States to be handed over to the authority of External Affairs, Defence, and Communications to the Indian Dominion. The Integration of Princely states had taken proper shape in his leadership.
