The correct answer is: D) All of the above.
Operation Polo was a military operation launched by the Indian Armed Forces on 13 September 1948 to annex the princely state of Hyderabad, which was then ruled by the Nizam Osman Ali Khan. The operation was successful, and Hyderabad was integrated into India on 17 September 1948.
The Nizam was a Muslim ruler, and Hyderabad was a Muslim-majority state. However, the Indian government was concerned that the Nizam might align himself with Pakistan, and it was also concerned about the growing communist movement in Hyderabad. The Telangana Rebellion, which was a peasant uprising against the Nizam’s rule, had also begun in 1946.
The Indian government decided to launch Operation Polo to prevent Hyderabad from joining Pakistan and to suppress the Telangana Rebellion. The operation was successful, and Hyderabad was integrated into India. The Nizam was deposed, and Hyderabad was merged with the Indian state of Andhra Pradesh.
The integration of Hyderabad into India was a controversial issue, and it led to violence and unrest in the state. However, the Indian government has maintained that the integration was necessary to prevent Hyderabad from joining Pakistan and to suppress the Telangana Rebellion.
