Answer 1

The correct option is C A and C are incorrect

The portal system is made up of capillaries and veins that collects deoxygenated blood from organs and supplies it to some other organs instead of supplying it directly to the heart. There are two types of portal systems in frog: renal portal system and hepatic portal system.
The renal portal system carries deoxygenated blood from the lower parts of the body (hind limbs) to kidneys. The hepatic portal system transports blood rich in nutrients from the alimentary canal to the liver.
