To identify the autoimmune disorders from the provided options, each condition is examined:
- Myasthenia gravis: An autoimmune disorder characterized by antibodies targeting muscle receptor sites, resulting in muscle weakness.
- Rheumatoid arthritis: An autoimmune condition where the immune system attacks the synovium, causing inflammation and joint damage.
- Gout: Caused by urate crystal accumulation in joints due to elevated uric acid levels; this is not an autoimmune disease.
- Muscular dystrophy: A category of genetic disorders leading to muscle weakness, not an autoimmune condition.
- Systemic Lupus Erythematosus (SLE): A chronic autoimmune disease impacting multiple bodily systems, leading to inflammation and tissue damage.
The autoimmune disorders identified are:
- A. Myasthenia gravis
- B. Rheumatoid arthritis
- E. Systemic Lupus Erythematosus (SLE)
Therefore, the correct selection is A, B, and E exclusively.
