Final answer:
The kidneys filter blood and create urine as part of the urinary system. The correct option is D.
Step-by-step explanation:
The organ that filters blood and creates urine is the kidney. The kidneys are two bean-shaped organs that are part of the urinary system, which also includes the ureters, urinary bladder, and urethra.
They play a crucial role in filtering wastes and excess water out of the blood, which is then formed into urine. The urine is then transported to the urinary bladder via the ureters and is stored there until it is eliminated from the body through the urethra.
