D. Probiont

Answer

To answer the question "The first living form resulting from the final stage of chemical evolution of life is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chemical Evolution**:
- Chemical evolution refers to the process by which simple organic compounds in the primordial environment gradually evolved into more complex molecules, leading to the first forms of life.

2. **Formation of Complex Organic Molecules**:
- In the primitive oceans, simple organic molecules combined to form complex organic compounds. This was a crucial step in the evolution of life.

3. **Development of Colloidal Aggregates**:
- These complex organic molecules formed large spherical colloidal aggregates. These aggregates are composed of macromolecules and are known as coacervates.

4. **Characteristics of Coacervates**:
- Coacervates are droplets that remain suspended in seawater. They are formed through the aggregation of colloidal particles, which are held together by a coating of lipid molecules.

5. **Role of Coacervates in Life Formation**:
- The coacervates serve as sites for chemical reactions, including the synthesis of RNA, DNA, and proteins. This is a significant step towards the emergence of life.

6. **Identification of the First Living Form**:
- The first living forms that emerged from these processes are referred to as protozoa or protobionts. These are considered the earliest forms of life.

7. **Conclusion**:
- Therefore, the correct answer to the question is that the first living form resulting from the final stage of chemical evolution of life is called a **protobiont**.

### Final Answer:
The first living form resulting from the final stage of chemical evolution of life is called a **protobiont**.
