The correct answer is: B) Protect tenant rights.
The Malabar Tenancy Act was passed in 1929 to protect the rights of tenants in the Malabar region of India. The Act gave tenants greater security of tenure and limited the amount of rent that they could be charged. It also established a system of tenancy courts to adjudicate disputes between landlords and tenants.
The Act was a significant step forward in the protection of tenant rights in India. It helped to improve the lives of millions of tenants and contributed to the development of a more equitable agrarian system.
Option A is incorrect because the Act did not abolish landlordism. Landlords were still allowed to own land and collect rent from tenants. However, the Act did limit the amount of rent that they could charge and gave tenants greater security of tenure.
Option C is incorrect because the Act did not introduce collective farming. Collective farming is a system of agriculture in which land is owned and worked by a group of people, usually as a cooperative. The Malabar Tenancy Act did not make any changes to the system of land ownership in Malabar.
Option D is incorrect because the Act did not promote agricultural development. The Act was primarily concerned with protecting the rights of tenants, not with promoting agricultural development.
