The Decreased Glomerular Filtration Rate in a Patient with Acute

The decreased glomerular filtration rate in a patient with acute glomerulonephritis is due to which pathophysiologic process?

A) Decreased renal-induced constriction of the renal arteries
B) Immune complex deposition, increased capillary permeability, and cellular proliferation
C) Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
D) Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis
