Answer

### Step-by-Step Solution:

1. **Identify the Question**: The question asks about the scientist who proposed the theory of Pangenesis.

2. **Review the Options**: The options provided are:
- A) Wiesmann
- B) de Vries
- C) Charles Darwin
- D) Lamarck

3. **Analyze Each Option**:
- **Wiesmann**: August Wiesmann was known for his theory of continuity of germplasm and opposed Lamarck's ideas about the inheritance of acquired characteristics. Therefore, he is not the correct answer.
- **de Vries**: He is known for the mutation theory of evolution and introduced the concept of "saltation". This does not relate to Pangenesis, so he is also not the correct answer.
- **Charles Darwin**: He proposed the theory of Pangenesis, suggesting that minute particles called "gemmules" are produced by all parts of the body and contribute to the formation of the individual. This makes him the correct answer.
- **Lamarck**: He is famous for his theory of inheritance of acquired characteristics, which is unrelated to Pangenesis.

4. **Conclude the Correct Answer**: Based on the analysis, the correct answer to the question is **C) Charles Darwin**.
