Part of the sensitivity report of an LP is shown below Variable Cells Final Reduced Objective Allowable Allowable Cell Name Value Cost Coefficient Increase Decrease $C$7 Values of decision variables x1 2 1E+30 $D$7 Vakues of decision variables x2 -5 -1 1E+30 E$T Vakes of decision variables x3 3' 1E+30 The value of the objective coefficient for decision variable x2 is changed to 5. Select one: The (non-zero) variables in the optimal mix will change and the optimal value might change. The (non-zero) variables in the optimal mix will not change but the optimal value will change. The (non-zero) variables in the optimal mix will change but the optimal value Will not change. There will be no impact on the optimal solution. In the Excel Solver tool, the appropriate choice for the solution tool is Select one: Evolutionary The choice does not matter, all will lead to a global optimum if it exists Simplex LP GRG Nonlinear
