The correct option is B regeneration
Regeneration is a mode of asexual reproduction where a whole new organism arises from a part of the parent body. Example: Planaria. If a Planaria is cut into 2 or more pieces, each piece will give rise to a new Planaria.
Regeneration is also a process of growth where an organism restores a lost part of its body. When the tail of a lizard is cut off, it regrows.
Metamorphosis is a process where, after birth, an organism undergoes multiple stages of marked changes in the structure to become an adult. Example: Tadpole of a frog into an adult frog.
Alternation of generation is the phenomena where an organism alternates between asexual and sexual phases during its life cycle. Example: Jellyfish alternates between a sexual phase called medusa and an asexual phase called a polyp.
Bioluminescence is a characteristic feature of Ctenophores, where they emit light.
