The correct answer is (a).
The Integrated Rural Development Programme (IRDP) was a poverty alleviation programme launched in India in 1978. The programme was designed to provide financial assistance and other support to poor families in rural areas. The strategy adopted under IRDP in the Seventh Plan was the adoption of a total household approach. This approach involved identifying all the poor families in a village and providing them with assistance based on their needs. The assistance provided under IRDP included loans, subsidies, and training. The objective of the total household approach was to ensure that all poor families in rural areas had access to the resources they needed to improve their livelihoods.
The other options are incorrect because they do not reflect the strategy adopted under IRDP in the Seventh Plan. The village approach involves identifying all the poor families in a village and providing them with assistance based on the needs of the village as a whole. The block approach involves identifying all the poor families in a block and providing them with assistance based on the needs of the block as a whole. The district approach involves identifying all the poor families in a district and providing them with assistance based on the needs of the district as a whole.
