If six units of capital can be substituted for one unit of labor without changing total steel output, whereas 4 units of capital can be substituted for one unit of labor without changing the output of wheat, at that moment: (w) there is an optimal allocation of resources in between wheat and steel. (x) this would be more efficient when labor was reallocated from wheat to capital and steel was reallocated from steel to wheat. (y) this would be more efficient to reallocate labor by steel to wheat and capital by wheat to steel. (z) there is inadequate information to answer above question definitively.
Please suggest me your advice for the same.
