Answer

D

Explanation

1. On an average, 1100 to 1200 ml of blood is filtered by the kidneys per minute which constitute roughly `1//5^(th)` of the blood pumped out by each ventricle of the heart in a minute. 
2. The glomerular capillary blood pressure causes filtration of blood through 3 layers, i.e., the endothelium of glomerular blood vessels, the epithelium of Bowman’s capsule and a basement membrane between these two layers.
