D. Linnaeus.

Answer

**Step-by-Step Solution:**

1. **Identify the Scientists Listed:**
The question provides four options: Pasteur, Oparin, Darwin, and Linnaeus. We need to determine which of these scientists made significant contributions specifically in the field of classification.

2. **Analyze Contributions of Each Scientist:**
- **Pasteur:** Known for his work in microbiology, particularly in the development of pasteurization and vaccines.
- **Oparin:** Recognized for his theories on the origin of life and contributions to biochemistry.
- **Darwin:** Famous for his theory of evolution and natural selection, which relates to the evolutionary classification of organisms but not directly to the classification system itself.
- **Linnaeus:** Developed the system of taxonomy known as Linnaean taxonomy and introduced the concept of binomial nomenclature for naming organisms.

3. **Determine the Scientist Related to Classification:**
Among the four scientists, Linnaeus is the one who made a significant contribution to the field of classification. He created a systematic way to classify and name organisms, which is foundational in biology.

4. **Conclude the Answer:**
The correct answer to the question is **Linnaeus**, as he is the scientist who made significant contributions in the field of biological classification.

**Final Answer:**
The scientist who made significant contributions in the field of classification is **Carl Linnaeus**.
