A. Unit Variables
B. Basic Variables
C. Non basic Variables
D. None of the above
✅ The correct answer is option B.
The variables whose coefficient vectors are unit vectors are called basic variables. The basic variables can be defined as the m variables which can take any value other than zero. Moreover, if the variables satisfy the non-negativity condition of the LP model, the basic solution created by them is called the basic feasible solution. The remaining variables are known as the non-basic variables.
