Explanations:The political status of Jammu and Kashmir underwent a significant change in 2019. Prior to this, Jammu and Kashmir was a state with a special status under Article 370 of the Indian Constitution, which granted it a certain degree of autonomy. However, in August 2019, the Indian government, led by Prime Minister Narendra Modi, abrogated Article 370 and reorganized the state into two Union Territories: Jammu and Kashmir, and Ladakh.
The decision to convert Jammu and Kashmir from a state to a Union Territory was part of a broader political and administrative restructuring of the region. The reorganization was implemented through the Jammu and Kashmir Reorganization Act, 2019, which was passed by the Indian Parliament. This act effectively dissolved the state of Jammu and Kashmir and created two Union Territories: Jammu and Kashmir, which has a legislature, and Ladakh, which does not have a legislature.
The reorganization of Jammu and Kashmir into Union Territories was a controversial move, with supporters arguing that it would lead to better governance and development, while critics contended that it undermined the region's autonomy and could exacerbate tensions. The decision was made following a series of political and security-related events, including the revocation of the special status and the imposition of a lockdown in the region.
It is important to note that the status change of Jammu and Kashmir in 2019 was a unique event and did not affect other states in India. States like Uttarakhand and Chhattisgarh, which were mentioned in the other options, did not undergo any similar status changes in 2019. Therefore, the correct answer to the question is that Jammu and Kashmir became a Union Territory in 2019.
