B. taxonomy and phylogeny
C. both (1) and (2)
D. none of the above

Answer

To solve the question regarding what the term "systematics," as used by Linnaeus, includes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Systematics**:
- Systematics is a branch of biology that deals with the classification and naming of organisms. It aims to understand the evolutionary relationships among various biological species.

2. **Origin of the Term**:
- The term "systematics" is derived from the Latin word "Systema," which means a systematic arrangement of organisms. This indicates that systematics involves organizing living things based on their relationships and characteristics.

3. **Linnaeus' Contribution**:
- Carl Linnaeus, a Swedish botanist, is known for formalizing the system of naming organisms called binomial nomenclature. He used the term "systematics" in his work, particularly in his book titled "Systema Naturae."

4. **Components of Systematics**:
- Systematics includes:
- **Diversity of Organisms**: Understanding the variety of life forms.
- **Taxonomy**: The science of classification of organisms.
- **Phylogeny**: The study of the evolutionary history and relationships among species.

5. **Evaluating Options**:
- Given the options:
- A: Diversity of organisms
- B: Taxonomy and phylogeny
- C: Both A and B
- D: None of the above
- Since systematics encompasses both the diversity of organisms and the aspects of taxonomy and phylogeny, the correct answer is **C: Both A and B**.

### Final Answer:
The term "systematics," as used by Linnaeus, includes both the diversity of organisms and the fields of taxonomy and phylogeny. Therefore, the correct option is **C: Both A and B**.
