The following tableau of the dual problem of a standard minimum problem is


Y1 Y2 Y3 X1 X2 X3 W
[ 0 1 0 1.5 2.2 -1.4 0 | 40.5 ]
[ 1 0 0 3.0 -1.6 4.2 0 | 65.2 ]
[ 0 0 1 -2.7 5.1 1.3 0 | 28.1 ]
______________________
[ 0 0 0 3.5 4.0 2.4 1 | 898.4 ]



A. Z = 898.4 at (65.2, 40.5, 28.1)
B. Z = 898.4 at (40.5, 65.2, 28.1)
C. Z = 898.4 at (3.5, 4.0, 2.4, 1)
D. Z = 898.4 at (3.5, 4.0, 2.4)
