A. Slack Variable
B. Surplus Variable
C. Artificial Variable
D. None of the above
✅ The correct answer is option C.
In simplex method, we add artificial variable variables in the case of ‘=’. In order to use the simplex method on problems with mixed constraints, we turn to a device called an artificial variable. This variable has no physical meaning in the original problem and is introduced solely for the purpose of obtaining a basic feasible solution so that we can apply the simplex method.
