Explanation:

• The National Food for Work Programme (NFWP), 2004 was launched by the Ministry of Rural Development, central government on 14 November 2004 in 150 of the most backward districts of India to generate supplementary wage employment.
• Food grains are provided to the States free of cost. The transportation cost, handling charges, and taxes on food grains will, however, be the responsibility of the States.
• The eligibility criteria were relaxed to provide for both Below Poverty Line (BPL) and Above Poverty Line (APL) families. This is one of a number of schemes built on the food for work concept.
• Option 1: Rural Landless Employment Guarantee Programme (RLEGP) was introduced later as a poverty alleviation scheme but it wasn't a renaming of the Food for Work programme.
• Option 2: National Rural Employment Programme (NREP) was another employment scheme that provided work opportunities but was separate from the Food for Work initiative.
• The Food For Work Programme was restructured and renamed as National Rural Employment Programme in October 1980 by the then Prime Minister Indira Gandhi and it became a regular Programme from April 1981. In 1989 NREP was merged with Jawahar Rozgar Yojana.
• Option 3: Jawahar Rozgar Yojana (JRY) was launched in 1989 by merging NREP and RLEGP.
• Jawahar Rozgar Yojana (JRY) was launched on April 1, 1989 by merging National Rural Employment Programme and Rural Landless Employment Guarantee Programme by Prime Minister Rajiv Gandhi. The urban version of this program was Nehru Rozgar Yojana.- Option 4: Integrated Rural Development Programme (IRDP) focused on providing employment and promoting rural industries but wasn’t a renamed version of the Food for Work programme.
• The programme has since been subsumed in National Rural Employment Guarantee Act (NREGA) of 2005 which has come in force in 200 identified districts of the country including 150 NFFWP districts. MGNREGA is now the chief right based employment guarantee scheme.
