The correct answer is: A. Odisha
The States Reorganisation Commission (SRC) was set up in 1953 to review the existing administrative arrangements for the Indian states and to recommend such changes as might be necessary to ensure that these arrangements were in consonance with the requirements of linguistic homogeneity and administrative convenience.
The SRC submitted its report in 1955, and one of its recommendations was that the state of Bihar should be divided into two states, Bihar and Odisha. This recommendation was accepted by the government of India, and the two states were formed on 1 November 1956.
The areas of Bihar that were transferred to Odisha included the following:
- The districts of Angul, Cuttack, Dhenkanal, Gajapati, Ganjam, Koraput, Mayurbhanj, Puri, Sambalpur, and Sundargarh.
- The princely states of Baudh, Khandapara, and Patna.
- The Oriya-speaking areas of the districts of Balasore, Bhadrak, Keonjhar, and Mayurbhanj.
The transfer of these areas to Odisha was a major step in the process of linguistic reorganisation of the Indian states. It helped to create a more homogeneous state of Odisha, and it also paved the way for the development of the state’s economy and culture.
The other options are incorrect because they do not correspond to the areas of Bihar that were transferred to Odisha.
