The recommended treatment for PKU is a low-protein diet supplemented with a special formula that is free from phenylalanine. This helps to limit the amount of phenylalanine that is consumed and prevent its accumulation in the body. Patients with PKU also need to avoid certain foods that are high in phenylalanine, such as meat, fish, eggs, and dairy products. Vitamin B12 supplements and surgery are not effective treatments for PKU, as the disorder is caused by a genetic defect in the metabolism of phenylalanine. Hence option B is correct.

Option(A) The recommended treatment for PKU is a low-protein diet supplemented with a special formula that is free from phenylalanine. Hence option A is incorrect.

Option(C) The recommended treatment for PKU is a low-protein diet supplemented with a special formula that is free from phenylalanine. Hence option C is incorrect.

Option(D) The recommended treatment for PKU is a low-protein diet supplemented with a special formula that is free from phenylalanine. Hence option D is also incorrect.
