Solution

The correct option is B
Open & Haemocoel

Most Invertebrates consist of the open type circulatory system. Here, the blood, which is very dissimilar to our own, flows through a general body cavity called the haemocoel. Here the transfer of nutrients and oxygen happens through simple diffusion and is sufficient and suited for the smaller bodies of the invertebrates.
