The correct answer is: at every points of the segment joining two points
The graph of the feasible region for the given L.P.P is

 
The value of objective function at corner points are
z= [ x 1 + x 2 ] O =0
z= [ x 1 + x 2 ] E =6
z= [ x 1 + x 2 ] F =10
z= [ x 1 + x 2 ] G =10
z= [ x 1 + x 2 ] D =5
Since the objective function is maximized at both points F and G, hence it will have a maximum value at every points of the segment joining points F and G
