B. 1,1,2
C. 1,2, many
D. 2,2, many.

Answer

To determine the number of cotyledons in Zea, Cycas, and Pinus, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Zea**:
- Zea is the scientific name for maize (corn).
- Maize is classified as a monocotyledon (monocot), which means it has **1 cotyledon**.

2. **Identify Cycas**:
- Cycas is a genus of gymnosperms, specifically a type of cycad.
- Gymnosperms typically have **2 cotyledons** in their seeds.

3. **Identify Pinus**:
- Pinus is a genus of gymnosperms, commonly known as pines.
- Pines can have a variable number of cotyledons, but they typically have **many cotyledons** (usually between 2 to 5, depending on the species).

4. **Compile the Information**:
- Zea: 1 cotyledon
- Cycas: 2 cotyledons
- Pinus: many cotyledons

5. **Final Answer**:
- Therefore, the number of cotyledons in Zea, Cycas, and Pinus respectively are **1, 2, and many**.

### Conclusion:
The correct answer is **1-2-many**.
