Answer : 1. "Systematic lupus erythematosus"
Explanation :

Answer: A) Systematic lupus erythematosus Explanation: An autoimmune disease is a condition in which your immune system mistakenly attacks your body.   The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them. Normally, the immune system can tell the difference between foreign cells and your own cells.   In an autoimmune disease, the immune system mistakes part of your body — like your joints or skin — as foreign. It releases proteins called autoantibodies that attack healthy cells. Some autoimmune diseases target only one organ. Type 1 diabetes damages the pancreas. Other diseases, like lupus, affect the whole body.   Hence, Systematic lupus erythematosus is an autoimmune disease that affects multiple organs.
