Heterophylly under different environmental conditions is shown by

Options

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

Answer

To solve the question regarding which plant exhibits heterophylly under different environmental conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Heterophylly**:
- Heterophylly refers to the phenomenon where a single plant exhibits different types of leaves (morphological variations) depending on environmental conditions or different life stages.

2. **Identify the Options**:
- The options provided are:
- A) Buttercup
- B) Cotton
- C) Coriander
- D) Larkspur

3. **Analyze Each Option**:
- **Buttercup**: Known to have different leaf forms depending on whether it is growing in aquatic or terrestrial environments. This shows adaptation to different environmental conditions.
- **Cotton**: Generally does not show significant variation in leaf shape based on environmental conditions.
- **Coriander**: Primarily has a consistent leaf shape regardless of environmental changes.
- **Larkspur**: Similar to cotton and coriander, it does not exhibit significant heterophylly.

4. **Conclusion**:
- Based on the analysis, **Buttercup** is the only plant among the options that demonstrates heterophylly due to its adaptation to different environmental conditions (aquatic vs terrestrial).

5. **Final Answer**:
- The correct answer is **A) Buttercup**.
