QUESTION 18 a. Which statement pertaining to LP problems is incorrect? When the coefficients of the objective function are proportional (i.e., parallel) to the coefficients of a binding constraint, there will be alternative optima. O b. If the feasible region of an LP problem is unbounded, we can conclude immediately that the problem is infeasible. A primal problem that follows the form of a cost-benefit-trade-off problem will have a dual problem that will follow the form of a resource allocation problem. A primal problem that follows the form of a resource allocation problem will have a dual problem that will follow O d. the form of a cost-benefit-trade-off problem. C. O e. The value of the dual variable (or shadow price) for a non-binding primal constraint is 0
