The correct answer is: a) Concerns about regional disparities with Telangana.
The Jai Andhra movement was a political movement in the Indian state of Andhra Pradesh that sought to create a separate state of Andhra out of the Telugu-speaking areas of the state. The movement was launched in the 1970s in response to concerns about regional disparities between the Telangana and Andhra regions of the state.
The Telangana region was historically more developed than the Andhra region, and this disparity had led to resentment among the people of Andhra. The Jai Andhra movement sought to address this disparity by creating a separate state of Andhra that would be more equitable for all its people.
The movement was successful in achieving its goal, and the state of Andhra Pradesh was divided into two states, Andhra and Telangana, in 2014.
The other options are incorrect because they do not accurately reflect the reasons for the Jai Andhra movement.
Option b) is incorrect because the imposition of Hindi as the national language was not a major concern of the Jai Andhra movement.
Option c) is incorrect because border disputes with neighboring states were not a major concern of the Jai Andhra movement.
Option d) is incorrect because centralization of power was not a major concern of the Jai Andhra movement.
