Choose incorrect statement regarding regeneration.
a) Formation of whole body from a small fragment
b) Replacement of the lost part
c) Growth of a small bud from the body
d) Planaria is a common example

Options

A. Formation of whole body from a small fragment
B. Replacement of the lost part
C. Growth of a small bud from the body
D. Planaria is a common example

Answer

To solve the question regarding regeneration, we need to analyze each of the provided statements one by one to identify the incorrect one.

### Step-by-Step Solution:

1. **Statement A: Formation of whole body from a small fragment**
- This statement refers to the ability of certain organisms to regenerate a complete body from a small piece of themselves. This is true for organisms like planaria, which can regenerate an entire body from a small fragment.
- **Conclusion**: This statement is correct.

2. **Statement B: Replacement of the lost part**
- This statement describes the process of regeneration where lost body parts are replaced. For example, if an organism loses a limb, regeneration allows for the regrowth of that limb. This is a well-documented phenomenon in many species.
- **Conclusion**: This statement is correct.

3. **Statement C: Growth of a small bud from the body**
- This statement describes budding, which is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. This process is different from regeneration, which involves the regrowth of lost parts or the formation of a new organism from a fragment.
- **Conclusion**: This statement is incorrect as it describes budding rather than regeneration.

4. **Statement D: Planaria is a common example**
- Planaria are indeed well-known for their regenerative abilities. They can regenerate lost body parts and are often used in studies related to regeneration.
- **Conclusion**: This statement is correct.

### Final Answer:
The incorrect statement regarding regeneration is **C: Growth of a small bud from the body**.
