What are regenerative cells used by Hydra for?

Correct option is D

The correct answer is option (d) Hydra uses regenerative cells for reproduction by budding.

1. Hydra reproduces asexually through budding, a process where a small growth (bud) develops on the parent organism.
2. The regenerative cells play a crucial role in forming the bud by dividing and differentiating into various tissue types.
3. Once the bud matures, it detaches and becomes an independent organism.
