Options

A. Peduncle
B. Petiole of leaves
C. Leaf bases
D. Inflorescence

Answer

To answer the question about the formation of the pseudostem in banana plants, we can break down the information step by step:

### Step-by-Step Solution:

1. **Understanding the Structure of Banana Plant**:
- The banana plant has a unique shoot system where the true stem is located underground.

2. **Identifying the True Stem**:
- The true stem of the banana plant is modified and is found in the form of a rhizome, which is an underground stem.

3. **Pseudostem Formation**:
- The structure that appears above the ground is called the pseudostem. This pseudostem is not a true stem but is formed by the tightly packed leaf bases.

4. **Role of Leaf Bases**:
- The leaf bases, also known as hypopodium, contribute to the formation of the pseudostem. These leaf bases grow together and create a stem-like appearance.

5. **Suckers and Growth**:
- From the leaf bases, suckers can develop. These suckers grow horizontally and have nodes with scale leaves and auxiliary buds.

6. **Conclusion**:
- Therefore, the pseudostem in banana is formed by the leaf bases.

### Final Answer:
The pseudostem in banana is formed by the leaf bases.
