Which of these statements is best?
A)If all of a resource represented by a slack variable is used, that slack variable will not be in the production mix column of a linear programming simplex tableau.
B)In linear programs with many variables, even though we cannot graph the feasible region, the optimal solution will still lie at an interior point.
C)A surplus variable is added to a constraint in order to create an equality, and represents a quantity of unused resource.
D)If there are seven less-than-or-equal constraints in a problem, the simplex table contains seven surplus variables.
