Answer:
Option 3. Annelida .
explanation:
Metamerism or segmentation is the main characteristic feature of phylum annelida.
what is metamerism ?
metamerism is a phenomena in which body is divided into small segments. this this may be seen in the body of earthworms and other such worm like creatures.
more about phylum annelida
annelids are also known as roundworms. they can be found in water as well as moist soil. hence it is a large phylum as well. they are bilaterally symmetrical invertebrate organisms.
other options :
1) platyhelminthes
2) porifera
3) mollusca.
Here , none of them exhibit metamerism. platyhelminthes is the phylum composed of flatworms while porifera contains all the sponges ,they are composed of cells itself so there is no chances of segmentation in their body.
phylum mollusca basically contains the animals with shell and radula in their Bodies like octopus and pila . hence segmentation is absent in them also.
