Which of the following is a correct match?

Options

A. A.Weismann-Theory of Pangensis
B. Hugo-de-Vries--Genetic drift
C. Oparin-Origin of life
D. Thomas Malthus - Philosophique Zoologique

Answer

To solve the question "Which of the following is a correct match?", we need to analyze each option provided and determine if the associations are accurate.

### Step-by-Step Solution:

1. **Option A: August Weismann - Theory of Pangenesis**
- August Weismann is known for proposing the **Germplasm Theory**, which argues that hereditary information is transmitted through germ cells.
- The **Theory of Pangenesis** was actually proposed by **Charles Darwin**.
- Therefore, this option is **incorrect**.

2. **Option B: Hugo de Varies - Genetic Drift**
- Hugo de Varies is known for the **Mutation Theory**, which suggests that mutations are the primary source of genetic variation.
- **Genetic drift** is a different concept related to random changes in allele frequencies in a population, which was not proposed by de Varies.
- Thus, this option is also **incorrect**.

3. **Option C: Operon - Origin of Life**
- The term "operon" is typically associated with a unit of genetic regulation in prokaryotes, but the context here seems to refer to the **abiogenesis theory** of the origin of life.
- The theory of abiogenesis, which discusses how life could arise from non-living matter, is indeed associated with early scientific ideas about the origin of life.
- Therefore, this option is **correct**.

4. **Option D: Thomas Malthus - Philosophic Geological**
- Thomas Malthus is known for his work on population growth, specifically the **Malthusian Theory**, which discusses the relationship between population growth and food supply.
- The **Philosophic Zoologique** was written by **Jean-Baptiste Lamarck**, not Malthus.
- Hence, this option is **incorrect**.

### Conclusion:
After analyzing all options, the only correct match is **Option C: Operon - Origin of Life**.
