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

Options

A. deVries — Natural selection
B. Mendel — Theory of pangenesis
C. Weismann — Theory of continuity of germplasm
D. Pasteur — Inheritance of acquired characters

Answer

To solve the question, we need to identify which scientist is correctly matched with the theory they proposed. Let's analyze each option step by step:

### Step 1: Analyze the first option - Hugo de Vries
- **Claim**: Hugo de Vries proposed the theory of natural selection.
- **Reality**: This is incorrect. The theory of natural selection was proposed by Charles Darwin. Hugo de Vries is known for the mutation theory, which he developed while studying the evening primrose.

### Step 2: Analyze the second option - Gregor Mendel
- **Claim**: Mendel proposed the theory of pangenesis.
- **Reality**: This is also incorrect. Mendel is known for his laws of inheritance, which laid the foundation for genetics. Pangenesis was a theory proposed by Charles Darwin.

### Step 3: Analyze the third option - August Wiesmann
- **Claim**: Wiesmann's theory of continuity of germplasm.
- **Reality**: This is correct. August Wiesmann proposed the theory of continuity of germplasm, which states that somatic cells do not contribute to the germplasm and thus do not pass on acquired characteristics to the next generation.

### Step 4: Analyze the fourth option - Louis Pasteur
- **Claim**: Pasteur proposed the inheritance of acquired characters.
- **Reality**: This is incorrect. The inheritance of acquired characteristics was proposed by Lamarck. Pasteur is known for his work on the germ theory of disease.

### Conclusion
After analyzing all the options, the only correct match is:
- **August Wiesmann** with the **theory of continuity of germplasm**.

### Final Answer
The correct answer is **Option 3: August Wiesmann - Theory of continuity of germplasm**.
