Telangana officially became a separate state of India in:

1953
1956
2009
2014

The correct answer is D) 2014.

Telangana officially became a separate state of India on June 2, 2014. It was carved out of the southern state of Andhra Pradesh. The formation of Telangana was a long-standing demand of the people of the region, who felt that they were being discriminated against by the Andhra Pradesh government. The Telangana Rashtra Samithi (TRS), a regional political party, led the movement for statehood.

The TRS won a landslide victory in the 2014 assembly elections in Telangana. The party’s leader, K. Chandrashekar Rao, became the first chief minister of Telangana.

The formation of Telangana has been a major political development in India. It has led to the creation of a new state with a population of over 35 million people. The new state is expected to have a significant impact on the economy and politics of India.

Option A is incorrect because Telangana was not a separate state in 1953. It was part of the state of Hyderabad, which was ruled by the Nizam of Hyderabad.

Option B is incorrect because Telangana was not a separate state in 1956. It was part of the state of Andhra Pradesh, which was formed by the merger of the Telugu-speaking areas of Hyderabad and Andhra.

Option C is incorrect because Telangana was not a separate state in 2009. It was still part of Andhra Pradesh.
