Solution

The correct option is C Gastrovascular cavity
The primary organ of digestion and circulation in the Cnidaria is gastrovascular cavity. It is simple organization around the central cavity. In cnidarians, the gastrovascular cavity is also known as the coelenteron or 'blind gut', since, food enters and waste excretes through the same orifice. Thus, the correct answer is option C.
