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.
I would have to say b) a description or d) a statement hope that this helps if not message me
Not taking good care of themselves. Not being active, poor hygiene, bad diet, weak immune system etc
