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

Options

A. Weismann- Theory of continuity of germplasm
B. Pasteur- Inheritance of acquired characters
C. De Vries- Natural selection
D. Mendel-Theory of pangenesis

Explanation

To solve the question of which scientist's name is correctly matched with the theory put forth by him, we can follow these steps:

### Step 1: Analyze the Options
We need to look at each scientist mentioned in the options and the theories associated with them.

### Step 2: Identify the Theories
1. **Weismann - Theory of Continuity of Germplasm**: This theory states that only the germplasm (the genetic material) is passed from one generation to the next, while somatic cells do not contribute to heredity.

2. **Pasteur - Inheritance of Acquired Characters**: This theory is incorrectly attributed to Pasteur. It was actually proposed by Lamarck, who suggested that traits acquired during an organism's lifetime could be passed on to offspring.

3. **De Vries - Theory of Natural Selection**: This is incorrect as well. The theory of natural selection was proposed by Charles Darwin. De Vries is known for his mutation theory of evolution, which suggests that new species arise from mutations.

4. **Mendel - Theory of Pangenesis**: This is also incorrect. Mendel is known for his laws of inheritance, while the theory of pangenesis was proposed by Darwin, suggesting that all parts of the body contribute to the genetic material passed to offspring.

### Step 3: Conclusion
From the analysis, the only correct match is:
- **Weismann - Theory of Continuity of Germplasm**

### Final Answer
The scientist whose name is correctly matched with the theory put forth by him is **Weismann** with the **Theory of Continuity of Germplasm**.
