The correct answer is: A. 1834.
The Chota Nagpur Tenancy Act, also known as the Wilkin Law, was enacted in 1834. It was a landmark legislation that sought to protect the rights of the tribal people of Chota Nagpur. The Act was named after its author, Andrew Wilkin, who was the Commissioner of Chota Nagpur at the time.
The Wilkin Law was a major step forward in the history of tribal rights in India. It recognized the customary rights of the tribal people to land and other resources. It also established a system of courts to adjudicate disputes between tribal people and non-tribal people.
The Wilkin Law was a progressive piece of legislation, but it was not without its flaws. One of the main criticisms of the Act was that it did not go far enough in protecting the rights of the tribal people. The Act also failed to address the issue of land alienation, which was a major problem in Chota Nagpur at the time.
Despite its flaws, the Wilkin Law was a significant step forward in the history of tribal rights in India. It helped to protect the rights of the tribal people and to improve their lives.
The other options are incorrect because they are not the years in which the Wilkin Law came into existence.
