The correct option is B Regeneration of lost body parts
Epimorphosis is the regeneration of lost tissues or organs through the dedifferentiation of existing tissues, differentiated adult tissues. Adult cells dedifferentiate into a mass of cells and then re-differentiate into the new structure. For example, frog, newt and salamander limbs in which the lost portions of the limb are able to grow back. Thus, the correct answer is option B.
