The chronological order of these land reform-related initiatives is as follows:
1. Congress Agrarian Reform Committee (Kumarappa Committee) (B - 1949): Established by the Indian National Congress under J.C. Kumarappa, this committee recommended land reforms, including tenancy rights and land redistribution, setting the stage for post-independence policies.
2. Central Land Reforms Committee (A - Early 1950s): Formed under the Planning Commission during the First Five-Year Plan (1951–56), this committee focused on implementing land reforms like abolition of intermediaries and tenancy reforms, building on earlier recommendations.
3. National Commission on Agriculture (D - 1970–1976): Chaired by N.R. Mirdha, this commission provided comprehensive recommendations on agriculture, including land reforms, to enhance productivity and equity, culminating in its 1976 report.
4. National Agricultural Policy (C - 2000): Introduced by the Government of India, this policy addressed modern agricultural challenges, including land use and reforms, to promote sustainable farming and rural development.
Thus, the correct order is (B), (A), (D), (C), making option (3) correct.
