• B. Bowman’s capsule
• C. Neuron
• D. Collecting duct

Answer 1

The correct option is A

Nephron

The basic filtration unit of the kidney is called nephron. It is used to separate water, ions and small molecules from the blood, filter out wastes and toxins, and return the required molecules into the blood. Bowman's capsule is a cup-like sack at the beginning of the tubular component of a nephron in the kidney. Whereas, the collecting ducts of the kidneys are a network of small tubes that act as a drainage system in the body. Neuron is a nerve cell which is the basic building block of the nervous system.
