The Correct Option is C
Solution and Explanation
The renal portal system in frogs is a unique venous system. Blood from the hind limbs and tail drains into the renal portal veins, which then enter the kidneys before going to the heart. This allows the kidneys to filter blood from the lower body before it reaches the systemic circulation. This is distinct from the hepatic portal system, which connects the intestines to the liver.
