C. Syntype
D. Isotype

Answer

To solve the question "Species that cannot be divided into subspecies or varieties or races, is", we will analyze the given options step by step.

### Step 1: Understand the Options
The options provided are:
1. Polytypic
2. Monotypic
3. Syntype
4. Isotype

### Step 2: Define Each Term
- **Polytypic**: This term refers to a species that can be divided into two or more subspecies. Since the question asks for a species that cannot be divided, this option can be eliminated.

- **Monotypic**: This term refers to a species that is not divided into subspecies or varieties. This aligns with the requirement of the question, making it a strong candidate for the answer.

- **Syntype**: This term refers to any of two or more biological types that are listed in a description of a taxon. It does not pertain to the division of subspecies, so it can be eliminated.

- **Isotype**: In immunology, isotypes refer to the classification of antibodies into several types. This is unrelated to the classification of species, so it can also be eliminated.

### Step 3: Analyze the Best Option
From the definitions:
- Polytypic and Syntype do not fit the criteria of the question.
- Isotype is irrelevant to the context of species classification.
- Monotypic is the only term that fits the description of a species that cannot be divided into subspecies or varieties.

### Conclusion
The correct answer is **Monotypic** (Option 2).
