### Question Analysis
The question asks which type of lakes are characterized by low nutrient concentrations.

### Relevant Concepts
1. **Oligotrophic Lakes**: These lakes are typically deep, have clear water, and low nutrient concentrations.
2. **Eutrophic Lakes**: These lakes are rich in nutrients, leading to high productivity and often murky water.
3. **Dystrophic Lakes**: These lakes are characterized by high organic matter but can have variable nutrient concentrations.
4. **Endemic**: This term generally refers to species that are native to a specific area and does not directly relate to lake nutrient concentrations.

### Conclusion
Based on the definitions, *oligotrophic lakes* are the correct answer as they specifically refer to lakes with low nutrient concentrations.

### Final Answer
a. Oligotrophic
