Solution
The correct option is A20mmHg
The kidney plays the primary role in the formation of urine. Nephrons are the structural and functional unit of the kidneys. A tuft of capillaries present in nephrons is known as a glomerulus. This is a capillary network of complex anastomosing plexus of vessels and not of independent capillary loops. Blood enters the glomerulus through an afferent arteriole and leaves it through an efferent arteriole. Glomerular filtration takes place in the glomerulus. Then, blood plasma filters out from glomerulus into the glomerular capsule. This filtration is promoted by a pressure gradient of 10 - 15 mm Hg. So the nearest answer is option A
