| A. | The common region determined by all the constraints of LPP is called | I. | objective function |
| B. | Minimize z = C₁x1+C2x2+.....+Cnxn is | II. | convex set |
| C. | A solution that also satisfies the non-negative restrictions of a LPP is called | III. | feasible region |
| D. | The set of all feasible solutions of a LPP is a | IV. | feasible solution |

Assertion (A): The corner points of the bounded feasible region of a L.P.P. are shown below. The maximum value of \( Z = x + 2y \) occurs at infinite points.
Reason (R): The optimal solution of a LPP having bounded feasible region must occur at corner points.
