D. Telolecithal

Answer

To answer the question regarding the type of eggs laid by egg-laying mammals, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Egg Types**:
- Eggs can be classified based on the amount of yolk they contain. The classifications include:
- Alacythel: Almost no yolk.
- Microlacythel: Very little yolk.
- Mesolacythel: Moderate amount of yolk.
- Macrolacythel: Large amount of yolk.

2. **Identifying Egg-laying Mammals**:
- Egg-laying mammals, also known as monotremes (e.g., platypus and echidna), are unique among mammals because they lay eggs instead of giving birth to live young.

3. **Analyzing the Yolk Content**:
- The eggs of egg-laying mammals contain a significant amount of yolk, which is essential for the development of the embryo.

4. **Determining the Correct Classification**:
- Given that the eggs of egg-laying mammals have a large amount of yolk, they fall under the category of macrolacythel eggs.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the eggs of egg-laying mammals are **macrolacythel**.

### Final Answer:
The eggs of egg-laying mammals are **macrolacythel**.
