R.Virchow
R. Brown
Suttan & Boveri
Hanstein

Options

A. R.Virchow
B. R. Brown
C. Suttan & Boveri
D. Hanstein

Answer

To solve the question regarding who proposed the cell lineage or cell inheritance theory, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the scientist who proposed the cell lineage or cell inheritance theory.

2. **Define Cell Lineage Theory**: Cell lineage theory states that new cells arise from pre-existing cells. This means that all cells originate from other cells, which is a fundamental concept in biology.

3. **Review the Options**: The options given are:
- R. Virchow
- R. Brown
- Suttan & Boveri
- Hanstein

4. **Identify Contributions of Each Scientist**:
- **R. Virchow**: Proposed the cell lineage or cell inheritance theory, emphasizing that all cells come from pre-existing cells.
- **R. Brown**: Known for discovering the nucleus in cells, not related to cell lineage theory.
- **Suttan & Boveri**: Contributed to the chromosome theory, which pertains to genetics rather than cell lineage.
- **Hanstein**: Proposed the histogen theory, which is also unrelated to cell lineage.

5. **Conclusion**: Based on the definitions and contributions, the scientist who proposed the cell lineage or cell inheritance theory is **R. Virchow**.

### Final Answer:
The correct answer is **R. Virchow**.
