What is/are the purpose/purposes of 'District Mineral Foundations' in India? 1. Promoting mineral exploration activities in mineral-rich districts 2. Protecting the interests of the persons affected by mining operations 3. Authorizing State Governments to issue licences for mineral exploration Select the correct answer using the code given below.

District Mineral Foundations (DMFs) are statutory non-profit trusts established under the MMDR Amendment Act, 2015, specifically to work for the interest and benefit of persons and areas affected by mining-related operations. Statement 1 is incorrect because promoting mineral exploration is the objective of the National Mineral Exploration Trust (NMET), while licensing (Statement 3) remains a government regulatory function. This question tests the core concept of socio-economic welfare mechanisms for mining-affected communities, primarily implemented through the Pradhan Mantri Khanij Kshetra Kalyan Yojana (PMKKKY).
