The correct answer is: All of the above.
A salute state was a princely state in British India that was entitled to a personal salute of 11 or more guns. This indicated that the ruler of the state was a prince of high status. The three states mentioned in the question, Baroda, Bhavnagar, and Junagadh, were all salute states.
Baroda was a princely state in Gujarat, India. It was founded in 1721 by Pilaji Gaekwad, a Maratha general. The Gaekwads were the rulers of Baroda until 1947, when the state acceded to India.
Bhavnagar was a princely state in Gujarat, India. It was founded in 1723 by Bhavsinhji Gohil, a Rajput prince. The Gohils were the rulers of Bhavnagar until 1947, when the state acceded to India.
Junagadh was a princely state in Gujarat, India. It was founded in 1472 by Jam Junagadhji, a Rajput prince. The Jams were the rulers of Junagadh until 1947, when the state acceded to Pakistan. However, the people of Junagadh overwhelmingly voted to join India, and the state was eventually merged with India in 1948.
All three of these states were important princely states in British India. They were all ruled by powerful dynasties, and they all played a significant role in the history of India.
