(2,3) O (3,2) (3,1) (2.1) OPivoting is not the correct action for this tableau. ONone of the above. Ln 17.A certain number of steps of the simplex method results in the following simplex tableau. 0 0 1 3 0 0 0 5 0 0 0 2 0 0 0 1 2 51 0 10 2 20 1 3 0 0 20 100 3 0 1 If the simplex method is not complete, state the next pivot location. If the simplex method is complete, list the maximum and the location of the solution. The method is complete and the solution is a maximum of 100 at (4,10,0) Pivot about the (1,3) coordinate. The method is complete and the solution 100 at (0,4,10). OPivot about the (2,1) coordinate. The method is complete and there is no solution. None of the above. is a maximum of
