Which of the following groups of states has the largest concentration of rural poor and people living below the poverty line?

When evaluating these comparative options, Group A (Karnataka, Maharashtra, Goa) contains states with high absolute regional counts of rural distress and poverty pockets (such as inside the dry interior blocks of North Karnataka and the Vidarbha/Marathwada regions of Maharashtra), outstripping the relative proportions present in groups heavily weighted with low-poverty states like Kerala or Goa.
