If an LPP admits optimal solution at two consecutive vertices of a feasible region, then
the LPP under consideration is not solvable
the LPP under consideration must be reconstructed
the required optimal solution is at the mid-point of the line joining two points
the optimal solution occurs at every point on the line joining these two points
D.
the optimal solution occurs at every point on the line joining these two points
If an LPP admits optimal solution at two consecutive vertices of a feasible region, then the optimal solution occurs at every point on the line joining these two points.
