Solution
The correct option is D negative The glomerular filtration barrier has charge selectivity. The three-layered barrier consists of the fenestrated endothelium, podocyte foot processes with bridging slit diaphragms, and the intervening glomerular basement membrane. Negative charge is associated with each of the three layers and this retards filtration by repelling all negatively charged components of plasma e.g albumin.
