The extreme xerophytic condition is shown by

Options

A. Brassica
B. Capparis
C. Cactus
D. Nerium

Explanation

To solve the question regarding which plant shows extreme xerophytic conditions, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Xerophytic Conditions**:
- Xerophytic conditions refer to adaptations of plants that allow them to survive in extremely dry environments. These adaptations are crucial for water conservation.

2. **Identify Key Adaptations**:
- Xerophytic plants often exhibit specific adaptations such as:
- Modified leaves that may turn into spines to reduce water loss.
- Thick, fleshy stems that store water.
- A waxy coating on leaves or stems to minimize evaporation.

3. **Evaluate the Given Options**:
- The options provided are:
- Brassica
- Caparis
- Cactus
- Nerium

4. **Analyze Each Option**:
- **Brassica**: Typically found in temperate climates, not adapted to extreme dryness.
- **Caparis**: Some species can tolerate dry conditions but are not extreme xerophytes.
- **Cactus**: Well-known for its extreme adaptations to dry environments, including spines instead of leaves and water-storing stems.
- **Nerium**: While it can tolerate drought, it does not exhibit the extreme adaptations seen in cacti.

5. **Conclusion**:
- Among the options, **Cactus** is the plant that shows the most extreme xerophytic conditions due to its specialized adaptations for surviving in arid environments.

### Final Answer:
The extreme xerophytic condition is shown by **Cactus**.
