Answer 2

Answer:

• The correct answer is B.) Regeneration.

Explanation:

• Regeneration is a process in which lost or wounded parts of the body is regained by the organisms through the regenerative powers of the cells.

• Humans and other higher animals have very limited regenerative power, but in lower animals like Planaria, hydra, starfish, etc the regenerative powers are exceptional therefore new organisms can also be grown through this process.

• And in lower organisms it acts as a process of asexual reproduction.

• Starfish which belongs to phylum Echinodermata also has a remarkable power of regeneration and hence a single piece of starfish can grow into a new organism.
