Solution
The correct option is C Metamerism
- Metamerism is true segmentation where external divisions correspond to internal divisions (hence, compartments in the body). It is the phenomenon of having a linear series of body segments that are fundamentally similar in structure.
- Earthworm (an annelid) represents an example of metamerism.
- Metagenesis is an alternation of two life forms in an organism.
- Metamorphosis generally means a marked change in physical appearance from immature to adult.
So the correct answer is option b.
