The correct option is
C Immune-related disorder
Glomerulonephritis is inflammation of the glomeruli, which are structures in the kidneys that are made up of tiny blood vessels. It is an immune related disorder where immune complexes are deposited in the renal glomerulus where they bind complement and initiate an inflammatory process, attracting neutrophils and macrophages, resulting in an alteration of the basement layer of the kidney.
So, the correct answer is option C.
