(b) Segmentation
(c) Pseudocoelom
(d) Ventral nerve cord

Answer 1

Answer:

The answer is ventral nerve chord.

Answer 2

Not a characteristic of phylum Annelida:

• Option “C” is correct i.e. pseudocoelom..

• Pseudocoelom is not a characteristic of phylum Annelida.

• Annelids are the protostomes taking a series of rings or segments that mark up their whole body.  

• Annelids have a great, well-developed coelom and also have a closed circulatory system so pseudocoelom is not a characteristic of Annelida.
