C Correct answer
Explanation

Filtration occurs in the glomerulus, which is a network of capillaries enclosed by the Bowman's capsule. This structure filters water and small solutes out of the blood while retaining larger proteins and cells. The subsequent tubular parts of the nephron are primarily involved in reabsorption and secretion.
