$5$ pts

A linear program has been solved and sensitivity analysis has been performed. The ranges for the objective function coefficients have been found. For the profit on $x,$ the upper bound is $80,$ the lower bound is $60,$ and the current value is $75.$ Which of the following must be true if the profit on this variable is lowered to $70$ and the optimal solution is found?

The range of feasibility has been exceeded

A new corner point will become optimal

The optimal solution for all of the decision variables will remain the same

The range of optimality has been exceeded

A redundant constraint exists in the problem
