| List I | List II | 
|---|---|
| A. The region represented by \(x \geq 0, y \geq 0\) | I. no feasible region | 
| B. The region represented by the inequalities \(2x + y \geq 3, x + 2y \geq 6, x,y \geq 0\) | II. 1st quadrant | 
| C. The region represented by the inequalities \(x + 2y \leq 8, 3x + 2y \leq 12, x,y \geq 0\) | III. unbounded | 
| D. The region represented by the inequalities \(x + y \leq 2, 3x + 5y \geq 15, x,y \geq 0\) | IV. bounded | 
To match the regions given in list I with the descriptions in list II, we analyze each set of inequalities to determine the nature of the feasible region.
Thus, the correct option is: А-II, В-III, C-IV, D-I.

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.
