• A. Collecting duct
• B. Glomerulus
• C. Loop of Henle
• D. Renal pelvis

Answer: (B)

Verified step by step guidance

1. Understand the function of each kidney structure listed: the Collecting duct, Glomerulus, Loop of Henle, and Renal pelvis.
2. Recall that the primary process of removing waste products from the blood begins with filtration of plasma to form filtrate.
3. Identify that the Glomerulus is a network of capillaries located at the beginning of the nephron where blood plasma is filtered.
4. Recognize that the Collecting duct and Loop of Henle are involved in modifying the filtrate after it is formed, not in the initial filtration.
5. Note that the Renal pelvis is a funnel-shaped structure that collects urine after filtration and reabsorption processes are complete, not involved in filtration itself.
