Repetitive regeneration is found in
The process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage is called Repetitive regeneration. In Hydra, it occurs as foot regeneration arising from the basal part of the body, and head regeneration, arising from the apical region. Head regeneration requires complex reconstruction of the area, while foot regeneration is much simpler, similar to tissue repair.
So, the correct option is ‘Hydra’.
