To solve the question regarding what the petiole part of the leaf is known as, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Structure of a Leaf**:
- A leaf consists of several parts, including the lamina (the broad, flat part), the petiole (the stalk that connects the leaf to the stem), and the stipules (small leaf-like structures at the base of the petiole).

2. **Identifying the Petiole**:
- The petiole is specifically the stalk that attaches the leaf blade (lamina) to the stem of the plant. It plays a crucial role in supporting the leaf and facilitating the transport of nutrients and water.

3. **Analyzing the Options**:
- The options provided are:
- A) Epipodium
- B) Mesopodium
- C) Hypopodium
- D) None of these

4. **Defining the Terms**:
- **Epipodium**: Refers to the upper part or above the leaf.
- **Mesopodium**: This term is used to refer to the petiole, which is the middle part connecting the leaf to the stem.
- **Hypopodium**: Refers to the part below the leaf or the lower portion.

5. **Conclusion**:
- Since the petiole is the stalk that connects the leaf to the stem, it is correctly identified as the **mesopodium**. Therefore, the correct answer is **B) Mesopodium**.

### Final Answer:
The petiole part of the leaf is known as **Mesopodium**.
