Which of the following statements is true about lupus?

The statement that lupus is an autoimmune disease is correct. Lupus, specifically systemic lupus erythematosus (SLE), is a chronic condition in which the body's immune system mistakenly attacks its own tissues and organs, leading to inflammation and damage. This autoimmune response can affect various systems in the body, including the skin, joints, kidneys, heart, and more.

This distinction is crucial in understanding lupus, as it helps clarify why it is not contagious (contradicting the option suggesting it is a contagious disease). Furthermore, lupus does not primarily affect just one organ, such as the heart, as implied by another option; it has the potential to impact multiple systems simultaneously. Lastly, the idea that lupus eliminates inflammation is inaccurate since the disease is characterized by episodes of significant inflammation due to the autoimmune response.
