(2). A minimization LP is being solved by the big M method. e1 is the excess variable in constraint 1,s2 is the slack variable in constraint 2 , and a1,a3 are the artificial variables of constraints 1,3 respectively. The optimal is given below: Which one of the following statements is true. Explain briefly. (i). The original LP has a unique optimal solution. (ii). The original LP has multiple optimal solutions. (iii). The original LP is unbounded. (iv). The original LP has no feasible solution. (v) other
