Question

which of the following is not an organ of the urinary system?
a kidney
b bladder
c urethra
d liver

Explanation:

The urinary system consists of organs that produce, store, and eliminate urine. The kidney filters blood to form urine, the bladder stores urine, and the urethra is the tube through which urine exits the body. The liver, however, is part of the digestive system and is involved in functions like detoxification and metabolism of nutrients, not in the urinary system's processes.

Answer:

D. liver
