Study carefully the following statements and select the incorrect one(s).
(i). Lateralroots develop from pericycle.
(ii) . Endodermis is the innermost layer of cortex
(iii). Sapwood is the central, dark coloured, non-conducting part of secondary xylem.

Options

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

Explanation

To solve the question, we need to analyze each statement provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Evaluate Statement (i)**: "Lateral roots develop from pericycle."
- The pericycle is indeed the layer from which lateral roots arise in dicot roots. This statement is **correct**.

2. **Evaluate Statement (ii)**: "Endodermis is the innermost layer of cortex."
- The endodermis is located just inside the cortex and is considered the innermost layer of the cortex in roots. This statement is also **correct**.

3. **Evaluate Statement (iii)**: "Sapwood is the central, dark coloured, non-conducting part of secondary xylem."
- This statement is **incorrect**. In fact, sapwood is the lighter-colored, outer part of the secondary xylem that is responsible for conducting water. The central, dark-colored part is known as heartwood, which is non-conducting.

### Conclusion:
Based on the evaluations:
- Statement (i) is correct.
- Statement (ii) is correct.
- Statement (iii) is incorrect.

Thus, the incorrect statement is **(iii)**.
