Which one is correctly matched?

Options

A. Hugo de vreis: Natural selection
B. Darwin: Theory of Pangenesis
C. Pasteur: Theory of continuity of germplasm
D. Mendel: Inheritance of acquired characters

Answer

To determine which option is correctly matched in the question, we will analyze each option provided:

1. **Hugo de Vries - Natural Selection**:
- Hugo de Vries was a botanist known for proposing the mutation theory. He did not propose the theory of natural selection; that was proposed by Charles Darwin. Therefore, this match is incorrect.

2. **Darwin - Theory of Pangenesis**:
- Charles Darwin did propose the theory of pangenesis, which suggests that all body parts produce tiny particles called "gemmules" that contribute to the formation of gametes. This match is correct.

3. **Pasteur - Theory of Continuity of Germplasm**:
- Louis Pasteur was known for his work in microbiology and pasteurization, but he did not propose the theory of continuity of germplasm. This theory was proposed by August Weismann. Hence, this match is incorrect.

4. **Mendel - Inheritance of Acquired Characters**:
- Gregor Mendel is famous for his laws of inheritance and genetics. The concept of inheritance of acquired characters was proposed by Jean-Baptiste Lamarck, not Mendel. Therefore, this match is also incorrect.

Based on the analysis above, the only correctly matched option is:
- **Darwin - Theory of Pangenesis**.

### Summary of Correct Match:
- **Darwin - Theory of Pangenesis** is the correct match.
