The correct answer is D. Compression garments, exercise, and massage
Lymphedema occurs as lymph build-up and therefore liquid begins accumulating in the patient's body due to issues in the normal functions of the lymphatic system. In terms of control and treatment of lymphedema, most doctors advise the use of compression garments or bandages as this stops liquid from accumulating, also this is prevented by massages and exercise as they both help the fluid drain appropriately. Additionally, as lymphedema is not related to a bacterial infection or other conditions antibiotics or oxygen is never a strategy to control lymph building. Thus, the option with the correct strategies to control lymph building up is "Compression garments, exercise, and massage".
