Consider the following LPP :

Min Z = 2x1 + x2 + 3x3

Subject to :

x1 − 2x2 + x3 ≥ 4
2x1 + x2 + x3 ≤ 8
x1 − x3 ≥ 0
x1, x2, x3 ≥ 0

The solution of this LPP using Dual Simplex Method is :
(A) x₁=0, x₂=0, x₃=3 and Z=9
(B) x₁=0, x₂=6, x₂=0 and Z=6
(C) x₁=4, x₂=0, x₂=0 and Z=8
(D) x₁=2, x₂=0, x₂=2 and Z=10
