Provide an appropriate response.Solve the following linear programming problem using the simplex method:MaximizeP = 5x1 + 3x2subject to 2x1 + 4x2 ? 13 x1 + 2x2 ? 6 x1 , x2 ? 0
A. Maxi P = 9 when x1 = 0, x2 = 3 B. Max P = 30 when x1 = 6, x2 = 0 C. Max P = 18 when x1 = 0, x2 = 6 D. Max P = 32.5 when x1 = 6.5, x2 = 0
