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 increased $1080$ and the optimal solution is found?

The optimsisolution lor all of the decision vartibles will remain the same

Aredundant constraint exists in the problem

A new comer point will become optimal

The range of optimality has been exceeded and the LP must be recalculated
