The correct answer is: A. 16th October, 2019
The Legislative Council of Jammu and Kashmir was formally abolished on 16th October, 2019. The abolition was part of the Jammu and Kashmir Reorganisation Act, 2019, which also bifurcated the state into two union territories, Jammu and Kashmir and Ladakh.
The Legislative Council was a bicameral legislature, with the other house being the Legislative Assembly. The Legislative Council was composed of 42 members, 24 of whom were elected by the members of the Legislative Assembly and 18 of whom were nominated by the President of India.
The Legislative Council was abolished on the grounds that it was not necessary and that it was not being used effectively. The government argued that the Legislative Assembly was sufficient to represent the interests of the people of Jammu and Kashmir.
The abolition of the Legislative Council was controversial. Some people argued that it was a step towards the erosion of democracy in Jammu and Kashmir. Others argued that it was a necessary step to improve the efficiency of the government.
The abolition of the Legislative Council is a significant development in the history of Jammu and Kashmir. It remains to be seen whether it will have a positive or negative impact on the state.
