Four new road links A$,$ B$,$ C and D are to be constructed during a five$-$year plan period. Suggest the order of priority for phasing the road construction programme based on maximum utility approach. Assume utility units of $0\mathrm{.}5,1\mathrm{.}0,2$ and $4$ for four population ranges and $2,2$ and $5$ units per $1000$ t of agriculture, raw material and industrial products from the following data:$\backslash$table$[[\backslash$table$[[$Road$],[$Link$]],\backslash$table$[[$Length$],[$km$]],$No$.$ of villages served with population range,Productivity served, tAgricultural,$\backslash$table$[[$Raw$],[$material$]],\backslash$table$[[$Industrial$],[$product$]]],[$A$,65,30,15,10,3,8000,3000,1000],[$B$,25,20,8,6,3,5000,1000,1600],[$C$,30,15,6,5,5,6000,2000,3200],[$D$,40,40,4,3,2,3000,7000,500]]$
