Solution
The correct option is C Pseudocoelom
Pseudocoelom is not a character of Annelida. Phylum Annelida are coelomate animals.
Phylum Annelida have closed type of circulation, where blood flows through a system consisting of various blood vessels and is never exposed to the exterior body cavity.
In Annelida, the body is internally and externally segmented into a number of parts called a segment or metamere. These segments help the worm for locomotion.
Annelids and all other complex invertebrates share another characteristic feature, a ventral nerve cord with a pair of ganglia (or a single fused ganglion) in each segment, and longitudinal axon bundles between ganglia in adjacent segments.
