D. Rhytidome

Answer

To answer the question, "Which anatomical structure of Bhojpatra was used to write manuscripts by ancient writers?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify Bhojpatra**: Understand what Bhojpatra is. It is derived from the leaves of the Betula utilis tree, commonly known as the Himalayan birch.

2. **Understand its Use**: Recognize that ancient writers used Bhojpatra for writing manuscripts, particularly in Sanskrit. This indicates that the material must have properties suitable for writing.

3. **Examine the Options**: The question provides four options:
- a) Skele-bhag (Scaly bark)
- b) Ring-bhag (Ring bark)
- c) Heart-wood
- d) Righty dome (likely a misinterpretation of "Rind" or "Rind bark")

4. **Analyze Each Option**:
- **Scaly Bark**: This type of bark has a discontinuous structure and is not typically used for writing.
- **Ring Bark**: This is the correct choice. It is the part of the bark that contains cambium, which is crucial for the growth of the tree and is used for writing.
- **Heart-Wood**: This is the central, non-living part of the tree that provides support but does not conduct water or nutrients, making it unsuitable for writing.
- **Righty Dome**: This term seems to refer to the outer bark, which is not the primary structure used for writing.

5. **Conclusion**: Based on the analysis, the anatomical structure of Bhojpatra used for writing manuscripts by ancient writers is the **Ring Bark**.

### Final Answer:
The anatomical structure of Bhojpatra used to write manuscripts by ancient writers is the **Ring Bark**.
