Final answer:
When the kidney suffers an autoimmune inflammatory reaction, it can lead to glomerulonephritis, which is an inflammation of the glomeruli of the nephrons.
Step-by-step explanation:
When the kidney suffers an autoimmune inflammatory reaction, it can lead to glomerulonephritis. Glomerulonephritis is an inflammation of the glomeruli of the nephrons, which are responsible for filtering the blood and producing urine. The inflammation can cause the glomeruli to lose their ability to function effectively, resulting in symptoms such as excessive protein and blood in the urine, increased blood pressure, and fluid retention leading to edema. So, the correct answer is (a) glomerulonephritis.
