For a Linear Programming Problem (LPP), the given objective function \( Z = 3x + 2y \) is subject to constraints: \[ x + 2y \leq 10, \] \[ 3x + y \leq 15, \] \[ x, y \geq 0. \] 
The correct feasible region is:
The feasible region in a Linear Programming Problem (LPP) is the intersection of all constraint inequalities, representing the set of points satisfying every condition.
To determine this region:
- Graph each constraint on a coordinate plane:
1. The equation \( x + 2y = 10 \) defines a straight line.
2. The equation \( 3x + y = 15 \) defines another straight line.
3. The inequalities \( x, y \geq 0 \) restrict the region to the first quadrant.
- The feasible region is the bounded area enclosed by these lines that simultaneously satisfies all constraints.
Based on the graphical representation, the feasible region is the area bounded by points \( A, O, E, C \), specifically identified as region \( AOEC \).
