I believe the correct answer is A , but I am not 100% sure , hope I helped (:
If your lymphatic system stopped working properly fluid would build in your tissues and cause swelling. You could get infections, blockage and even cancer. If your immune system stopped working properly too then you would most likely die. Since your lymphatic system is down and your immune system is down it would weaken your body tremendously meaning the smallest cold could cause death.
Yes, it is.
That, in fact, is a responsibility that everyone should go through.
