The correct option is B In Bowman's capsule
Bowman's capsule are double-walled, the cup-shaped structure around the glomerulus of each nephron of the vertebrate kidney. It serves as a filter to remove organic wastes, excess inorganic salts, and water. The Bowman's capsule is an expansion at the closed end of a renal tubule. A kidney's renal corpuscle is composed of tangled clusters of blood capillaries, called a glomerulus, and a thin-walled, sac-like structure called the Bowman's capsule, which surrounds the glomerulus.
