The correct answer is: A) Hyderabad State.
After India’s independence in 1947, the Telangana region was part of the Hyderabad State. The Hyderabad State was a princely state ruled by the Nizam of Hyderabad. The Nizam was a Muslim ruler, and the majority of the population of the Hyderabad State was Hindu. The Nizam was reluctant to join the Indian Union, and there was a lot of tension between the Nizam and the Indian government. In 1948, the Indian government launched Operation Polo, which resulted in the annexation of the Hyderabad State into the Indian Union. The Telangana region was then merged with the Andhra State to form the Andhra Pradesh State.
The other options are incorrect. Option B is incorrect because the Madras State was a different state that was located in the southern part of India. Option C is incorrect because there was no separate Telangana State after India’s independence. Option D is incorrect because the Bombay State was a different state that was located in the western part of India.
