One hormone helps to produce new leaves, while the other promotes abscission of leaves . These are respectively

Options

A. ABA and Auxins
B. Cytokinins
C. Gibberellins and cytokinins
D. Etylene and Gibbenllins

Answer

To answer the question regarding the hormones that help in producing new leaves and promoting the abscission of leaves, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for two specific hormones: one that aids in the production of new leaves and another that promotes the abscission (the process of shedding) of leaves.

2. **Identifying the Hormones**:
- **Cytokinins**: This hormone is known to promote cell division and is crucial for the growth of new leaves. It stimulates the growth of shoots and leaves, making it the hormone responsible for producing new leaves.
- **Abscisic Acid (ABA)**: This hormone is involved in the process of abscission. It signals the plant to shed leaves when they are no longer needed, thus promoting the separation of leaves from the plant.

3. **Conclusion**: Based on the functions of these hormones, we can conclude that:
- The hormone that helps to produce new leaves is **Cytokinins**.
- The hormone that promotes the abscission of leaves is **Abscisic Acid (ABA)**.

### Final Answer:
The hormones are:
- Cytokinins (for new leaves)
- Abscisic Acid (ABA) (for abscission of leaves)
