In a minimization$$ problem, a positive improvement index in a cell indicates$$ that:

Part $2$

A$.$

there is degeneracy.

B$.$

the total cost will increase if units are reallocated to that cell.

C$.$

the total cost will decrease if units are reallocated to that cell.

D$.$

the problem has no feasible solution.

E$.$

the solution is optimal.
