C. Liliacae
D. Malvaceae

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Dormancy**: Seed dormancy refers to a period during which seeds are unable to germinate even under favorable conditions. This dormancy helps seeds survive unfavorable environmental conditions.

2. **Role of Hard Seed Coats**: Hard seed coats play a crucial role in seed dormancy. They are impermeable to water and oxygen, which prevents germination. This characteristic allows seeds to withstand harsh climatic conditions and periods of resource scarcity.

3. **Identifying the Group with Hard Seed Coats**: In the context of the question, we need to identify which of the provided groups (febesi, solanesi, lilyasi, malvesi) contains members that typically have hard seed coats.

4. **Analyzing the Options**:
- **Febesi**: This family includes legumes such as beans, cowpeas, and lentils, which are known to have hard seed coats.
- **Solanesi**: This family includes plants like tomatoes and potatoes, which do not typically have hard seed coats.
- **Lilyasi**: This family includes lilies, which also do not have hard seed coats.
- **Malvesi**: This family includes plants like cotton and okra, which do not have hard seed coats.

5. **Conclusion**: Based on the analysis, the presence of hard seed coats that contribute to seed dormancy is characteristic of members of the **febesi** family.

**Final Answer**: Seed dormancy is due to the presence of hard seed coats in the members of **febesi**.
