A two variable linear program has the following characteristics: The objective function maximizes 13X1 + 13X2; Constraint 1 states that X1 = 1; constraint 2 states that X2 = 10; constraint 3 states that X1 = 0; constraint 4 states that X2 = 0. Which of the following statements is true about the linear program? In the optimal solution, constraint 1 has a surplus of zero and constraint 2 has a surplus of 1. The optimal solution value is 143 and in the optimal solution, constraint 2 has slack variable = 0. = In the optimal solution, constraint 3 has a slack of O and the optimal solution value is 20. The linear program has no optimal solution and it cannot be solved ever
