In which of the following , plasticity can be seen due to the changing environment ?
(a) Cotton
(b) Coriander
(c) Butter Cup
(d) Larkspur

Options

A. Cotton
B. Coriander
C. Butter Cup
D. Larkspur

Answer

To solve the question regarding which plant shows plasticity due to changing environmental conditions, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Plasticity**:
- Plasticity refers to the ability of an organism to adapt to varying environmental conditions. This adaptability can manifest in different forms, such as changes in morphology, physiology, or behavior.

2. **Analyzing the Options**:
- **(a) Cotton**: Cotton plants typically have a consistent leaf structure and do not exhibit significant changes in response to environmental variations. Therefore, they show limited plasticity.

- **(b) Coriander**: Similar to cotton, coriander also has a relatively stable leaf structure and does not show considerable adaptability to environmental changes. Thus, it has low plasticity.

- **(c) Buttercup**: Buttercup plants are known for their ability to exhibit different types of leaves depending on their environment. They can have both small and large leaves, demonstrating heterophily, which is a clear sign of plasticity.

- **(d) Larkspur**: Larkspur generally has a consistent leaf form and does not show significant adaptability to environmental changes. Therefore, it also has low plasticity.

3. **Conclusion**:
- Among the options provided, the Buttercup (option C) is the only plant that demonstrates plasticity due to its ability to adapt its leaf structure in response to environmental changes.

### Final Answer:
The correct answer is **(c) Buttercup**.
