B. Plumule
C. Pedicel
D. Pneumatophore

Answer

To solve the question "Stem develops from ________ of the embryo of a germinating seed," we need to identify which part of the embryo gives rise to the stem.

### Step-by-Step Solution:

1. **Understand the Structure of the Embryo**: The embryo of a germinating seed consists of three main parts: the radical, the plumule, and the cotyledons.

2. **Identify the Function of Each Part**:
- **Radical**: This part develops into the root system of the plant.
- **Plumule**: This part develops into the shoot system, which includes the stem and leaves.
- **Cotyledons**: These are the seed leaves that provide nutrients to the developing plant.

3. **Determine Which Part Develops into the Stem**: Since the stem is part of the shoot system, it is the plumule that develops into the stem of the plant.

4. **Conclusion**: Therefore, the correct answer to the question is that the stem develops from the **plumule** of the embryo of a germinating seed.

### Final Answer:
Stem develops from **plumule** of the embryo of a germinating seed.
