C. Thomas Malthus - He has written Assay on population .
D. Hugo de Vries - Gave the theory of germplasm .

Answer

To determine which scientist and their contribution are not matched correctly, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze Option 1: O'Perrin and Haldane**
- Contribution: Most acceptable theory for the origin of life.
- Explanation: O'Perrin and Haldane proposed the primordial soup theory, which suggests that life originated from a mixture of organic compounds in the early Earth's oceans, energized by sunlight. This match is correct.

2. **Analyze Option 2: Charles Darwin**
- Contribution: Given the most acceptable theory for evolution of life.
- Explanation: Charles Darwin is known for his theory of natural selection, which explains how species evolve over time. This match is also correct.

3. **Analyze Option 3: Thomas Malthus**
- Contribution: Wrote an essay on population.
- Explanation: Thomas Malthus wrote "An Essay on the Principle of Population," where he discussed the effects of population growth. This match is correct as well.

4. **Analyze Option 4: Hugo de Vries**
- Contribution: Theory of germplasm.
- Explanation: Hugo de Vries is known for his theory of mutation, not the theory of germplasm. The germplasm theory was actually proposed by August Weismann. Therefore, this match is incorrect.

### Conclusion:
The scientist and contribution that are not matched correctly is **Option 4: Hugo de Vries with the theory of germplasm**. The correct contribution of Hugo de Vries is the **theory of mutation**.

### Final Answer:
**Option 4: Hugo de Vries - Theory of germplasm (incorrect match)**
