The stem branch used in layering is

Options

A. Upper branch
B. Young branch
C. Soft basal branch
D. Hard basal branch.

Answer

To solve the question regarding the type of stem branch used in layering, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Layering**:
- Layering is a method of vegetative propagation where roots develop on a stem while it is still attached to the parent plant.

2. **Identifying the Types of Branches**:
- The options given are:
A. Upper Branch
B. Young Branch
C. Soft Basal Branch
D. Hard Basal Branch

3. **Analyzing the Characteristics of Each Option**:
- **Upper Branch**: Generally, these branches are not ideal for layering as they are often too far from the ground.
- **Young Branch**: While young branches can be used, they may not be as effective as soft basal branches.
- **Soft Basal Branch**: These branches are characterized by new shoots that are soft and flexible, making them suitable for layering.
- **Hard Basal Branch**: These branches are older and woody, which are not conducive to root development during layering.

4. **Conclusion**:
- Based on the analysis, the most suitable option for layering is **C. Soft Basal Branch**. These branches allow for the formation of roots when covered with soil, facilitating successful layering.

### Final Answer:
The stem branch used in layering is **C. Soft Basal Branch**.
