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

Options

A. Mendel - Theory of Pangenesis
B. Weismann - Theory of continuity of gemplasm
C. Pasteur - Inheritance of acquired characters
D. Hugo de Vries - Natural selection

Answer

To determine which scientist's name is correctly matched with the theory they proposed, we need to analyze the options provided and the theories associated with each scientist.

### Step-by-Step Solution:

1. **Identify the Scientists and Theories**: We need to look at the names of the scientists and the theories they are associated with. The question provides multiple options, and we need to assess each one.

2. **Evaluate Each Option**:
- **Option 1**: This option states that Darwin proposed the theory of pangenesis. However, this is incorrect. Darwin did discuss pangenesis, but it is not the most widely recognized theory attributed to him. Instead, he is known for the theory of natural selection.
- **Option 2**: This option claims that Weismann proposed the theory of continuity of germplasm. This is correct. Weismann's theory states that only the germ cells (sperm and eggs) carry genetic information to the next generation, while somatic cells do not contribute to inheritance.
- **Option 3**: This option suggests that Pasteur proposed the inheritance of acquired characters. This is incorrect. The inheritance of acquired characteristics is attributed to Lamarck. Pasteur is known for his work on biogenesis and disproving spontaneous generation.
- **Option 4**: This option states that Hugo de Vries proposed natural selection. This is also incorrect. Hugo de Vries is known for the mutation theory, particularly his work with the evening primrose, while natural selection is primarily associated with Charles Darwin.

3. **Conclusion**: After evaluating all options, the only correct match is **Option 2**, which states that Weismann proposed the theory of continuity of germplasm.

### Final Answer:
The correct option is **Option 2: Weismann - Theory of Continuity of Germplasm**.
