Which of the following is not the lateral branches of the roots?

Options

A. Tertiary roots
B. Secondary roots
C. Primary root
D. More than one option is correct.

Answer

To determine which of the following is not a lateral branch of the roots, we need to understand the structure and classification of roots.

### Step-by-Step Solution:

1. **Identify the Types of Roots**: Roots can be classified into primary, secondary, and tertiary roots. The primary root is the first root that develops from the seed.

2. **Understand Lateral Branches**: Lateral branches of roots are those that extend horizontally from the primary root. These are typically known as secondary and tertiary roots.

3. **Define Each Type**:
- **Primary Root**: This is the main root that grows directly from the seed. It is not considered a lateral branch.
- **Secondary Roots**: These are the first set of lateral roots that grow from the primary root.
- **Tertiary Roots**: These are the roots that branch off from the secondary roots.

4. **Conclusion**: Since the primary root is the main root from which the lateral branches (secondary and tertiary roots) arise, it is not classified as a lateral branch. Therefore, the answer to the question is the primary root.

### Final Answer:
The primary root is not a lateral branch of the roots.
