C. trees
D. sea

Answer

To solve the question "Amphibians do not occur in," we will analyze the options provided and understand the habitats of amphibians.

### Step-by-Step Solution:

1. **Understanding Amphibians**:
- The term "amphibian" comes from the Greek words "amphi," meaning "both," and "bios," meaning "life." This indicates that amphibians have a dual life, typically involving both aquatic and terrestrial environments.

2. **Identifying Larval and Adult Stages**:
- Amphibians, such as frogs and toads, have a larval stage (e.g., tadpoles) that is aquatic. This means they live in water during this stage.
- The adult forms of amphibians are usually adapted to live on land, but they still require moist environments.

3. **Analyzing the Options**:
- **Option A: Land** - Amphibians do occur on land as adults, so this option is incorrect.
- **Option B: Freshwater** - Amphibians are primarily found in freshwater environments during their larval stage, making this option incorrect as well.
- **Option C: Trees** - Some amphibians, like certain frogs, inhabit trees (arboreal), so this option is also incorrect.
- **Option D: Sea** - Amphibians are not typically found in marine environments (the sea). They are primarily freshwater organisms.

4. **Conclusion**:
- Based on the analysis, the correct answer to the question "Amphibians do not occur in" is **Option D: Sea**.

### Final Answer:
Amphibians do not occur in the sea.
