When the right hand side of two constraints are each increased by one unit the objective function value will be adjusted by the sum of the constraints dual prices?

The range of feasibility measuresthe right-hand-side values for which the objective function value will notchange.the right-hand-side values for which the values of the decision variables will notchange.the right-hand-side values for which the dual prices will not change.each of these choices are true.When the right-hand sides of two constraints are each increased by one unit, theobjective function value will be adjusted by the sum of the constraints' dual prices.
