Solution

The correct option is B alimentary canal
Cloaca is a common vent for urinary tract, reproductive tract and alimentary canal in amphibians and reptiles for the discharge of faeces, urine and gametes. However, in mammals and birds, there are separate apertures for the discharge of faeces and urinogenital products.

Portal system is a part of circulatory system in which blood from capillaries of one organ is carried to capillaries of another organ via a group of veins. Example: Hepatic portal system

Notochord is a rod like structure that develops in embryonic stage in chordates which they may or may not retain throughout their life.

Hepatic portal vessels is a group of veins that transport blood from the capillaries of the intestine to capillaries of liver.
