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 maximum possible total profit may increaseNone of the answers are possibleA new corner point will become optimalThe solution values for all the decision variables will remain the sameA redundant constraint exists in the problem
