- Earthworm belongs to phylum Annelida and it does not have larvae in its life cycle.
- The earthworm mates and fertilizes the egg which is held in the protective cocoon. It hatches from the cocoon and burrows in the soil where it grows into a juvenile worm and finally into a mature worm. Hence, option B is correct.
