Dear professors can you help my Operations Research question?

Use the K-T conditions to find the optimal solution to the following concave NLP: (25 pts.) (Use K-T conditions and the multipliers A, and /y for the first and second constraint, respectively) max 2 = (49-4x1)x: +(30 - 8x2)x2 5xz St. *; 2xz x Sxz Select one: O a. Xi = 23.25. X2 = 7.5, X3= 11.625.11 = 0.12 = 0. O b. Xi = 5.8125, X2 = 1.875, X3= 2.90625.1, = 0.12 = 0. O c. x1 = 23.25, X2 = 7.5, X3= 11.625. 11 = 2.5, 12 = 0. O d. Xi = 11.625. x2 = 3.75. Xa= 5.8125, A1 = 2.5, 12 = 0. O ex1 = 5.8125, x2 = 1.875. X= 2.90625 X = 2.5. A2 = 0. O f. x1 = 11.625. x2 = 3.75, x3= 5.8125. N = 0.12 = 0.
