A. Relationship among all variables is linear
B. It has single objective function & constraints
C. Value of decision variables is non-negative
D. All of the above
✅ The correct answer is option A.
The distinguishing feature of an LP model is relationship among all variables is linear. The linear programming model is an algebraic description of the objective to be minimized and the constraints to be satisfied by the variables.
