Which of the following conditions is classified as an autoimmune disease, where the immune system attacks the body's own tissues?

An example of an autoimmune disease is type 1 diabetes, where the immune system mistakenly attacks and destroys the insulin‑producing cells in the pancreas. In this condition the body’s defenses treat those cells as foreign and release antibodies that kill them. Because the pancreas is part of the body’s own tissues, the disease is classified as autoimmune. For instance, a child with type 1 diabetes will need insulin injections because their own immune cells have destroyed most of the pancreas’s insulin‑producing cells.
