D. Lamarck

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who proposed the concept of biological species, also referred to as "biospecies."

2. **Identifying the Scientist**: The concept of biological species was introduced by the scientist Ernst Mayr.

3. **Defining Biological Species**: Ernst Mayr defined biological species based on two main criteria:
- **Interbreeding**: A biological species is a group of organisms that can interbreed and produce viable offspring. This means that members of the same species can reproduce successfully with each other.
- **Reproductive Isolation**: Members of a biological species are reproductively isolated from other groups. This means they cannot interbreed with members of other species.

4. **Evaluating Options**: The question likely provides multiple-choice answers. Based on the information:
- Option B (Ernst Mayr) is the correct answer.
- Other options such as Linnaeus, Lamarck, etc., are incorrect as they contributed to different aspects of biology (e.g., binomial nomenclature, theory of evolution).

5. **Conclusion**: The correct answer to the question is that the concept of biological species was given by Ernst Mayr.
