Which one of the following scientist's name is correctly matched with the theory put forth by him?

Options

A. de Vries- Natural selection
B. Medel- Theory of pangenesis
C. Weimann- Theory of continuity of germplasm
D. Pasteur - Inheritance of acquired Characters

Answer

To solve the question regarding which scientist's name is correctly matched with the theory put forth by him, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Evaluate the First Option: De Vries and Natural Selection**
- Hugo De Vries is known for proposing the **Mutation Theory**, which states that mutations in DNA can lead to changes in organisms that are heritable.
- **Natural Selection** was actually proposed by Charles Darwin.
- **Conclusion**: This option is incorrect.

2. **Evaluate the Second Option: Mendel and Theory of Pangenesis**
- Gregor Mendel is recognized for his **Laws of Inheritance**, which describe how traits are passed from parents to offspring through genes.
- The **Theory of Pangenesis** was proposed by Charles Darwin, not Mendel.
- **Conclusion**: This option is incorrect.

3. **Evaluate the Third Option: Weizmann and Theory of Continuity of Germplasm**
- August Weizmann is known for the **Theory of Continuity of Germplasm**, which states that germplasm (genetic material) is passed down through generations without change.
- **Conclusion**: This option is correct.

4. **Evaluate the Fourth Option: Pasteur and Inheritance of Acquired Characters**
- Louis Pasteur is famous for his work on the germ theory of disease and disproving spontaneous generation through experiments like the swan-necked flask experiment.
- The **Inheritance of Acquired Characters** was proposed by Jean-Baptiste Lamarck, not Pasteur.
- **Conclusion**: This option is incorrect.

### Final Answer:
The only correctly matched scientist and theory is **Weizmann with the Theory of Continuity of Germplasm**.
