Read the following statements and select the incorrect one.
(i) In reparative regeneration several body parts can develop e.g. broken tail of wall lizard.
(ii) Fragmentation occurs in algae and bryophytes only.
(iii) Exogenous budding occurs in certain annelids and urochordates.
(iv) A small shoot of plant with superior characters is called scion or graft.

Options

A. (i) and (iii)
B. (ii) and (iii)
C. (iii) and (iv)
D. (i) and (ii)

Answer

To solve the question, we need to analyze each of the provided statements and identify which one is incorrect.

### Step-by-Step Solution:

1. **Evaluate Statement (i)**:
- The statement claims that in reparative regeneration, several body parts can develop, such as the broken tail of a wall lizard.
- **Analysis**: Reparative regeneration refers to the process where damaged tissues or cells repair themselves. It does not involve the regeneration of entire body parts. Therefore, this statement is incorrect.

2. **Evaluate Statement (ii)**:
- This statement asserts that fragmentation occurs only in algae and bryophytes.
- **Analysis**: Fragmentation is a form of asexual reproduction that can occur in various organisms, including fungi and certain bacteria, not just algae and bryophytes. Hence, this statement is also incorrect.

3. **Evaluate Statement (iii)**:
- The statement mentions that exogenous budding occurs in certain annelids and urochordates.
- **Analysis**: Exogenous budding is indeed a form of asexual reproduction where a new organism develops from an outgrowth (bud) on the parent organism. This process is observed in some annelids and urochordates, making this statement correct.

4. **Evaluate Statement (iv)**:
- This statement describes a small shoot of a plant with superior characters as a scion or graft.
- **Analysis**: A scion is indeed a part of a plant that is grafted onto another plant to propagate superior traits. This statement is correct.

### Conclusion:
Based on the evaluations:
- **Incorrect Statements**: (i) and (ii)
- **Correct Statements**: (iii) and (iv)

Thus, the answer is that statements (i) and (ii) are incorrect.

### Final Answer:
The incorrect statements are (i) and (ii).
