Final answer:
Among the diseases listed, tuberculosis is not due to autoimmunity. It is a bacterial infection and not an autoimmune disorder like lupus, multiple sclerosis, or type 1 diabetes.
Step-by-step explanation:
The question asks which of the listed diseases is not due to autoimmunity. The diseases mentioned, which are autoimmune, include lupus (Systemic Lupus Erythematosus), multiple sclerosis, and type 1 diabetes, where the immune system attacks the body's own cells - insulin-producing cells in type 1 diabetes, myelin in multiple sclerosis, and a variety of cells and tissues in lupus. On the other hand, tuberculosis is caused by a bacterial infection (Mycobacterium tuberculosis) and is not an autoimmune disease.
