Options

A. Epipyllous roots
B. Epiphytic roots
C. Photosynthetic roots
D. Velamen roots.

Answer

To answer the question "The roots which arise from the leaf are:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about a specific type of root that originates from the leaf of a plant.

2. **Identifying the Type of Root**: Roots that arise from leaves are known as "epiphyllous roots". The term "epiphyllous" indicates that these roots develop from the leaf itself.

3. **Explanation of Epiphyllous Roots**: Epiphyllous roots have the unique ability to grow into new plants when they come into contact with the ground. This is a form of vegetative reproduction.

4. **Example of Epiphyllous Roots**: A well-known example of a plant that exhibits epiphyllous roots is Bryophyllum. In this plant, the leaves can give rise to roots that can develop into new plants.

5. **Eliminating Other Options**:
- **Epiphytic Roots**: These are roots found in epiphytic plants, which grow on other plants but do not arise from the leaves.
- **Photosynthetic Roots**: These roots contain chlorophyll and can perform photosynthesis, but they do not originate from leaves.
- **Velamen Roots**: These roots are present in epiphytic plants and are specialized for absorbing moisture from the air, not arising from leaves.

6. **Conclusion**: Based on the above information, the correct answer to the question is "epiphyllous roots".

### Final Answer:
The roots which arise from the leaf are called **epiphyllous roots**.
