Match the following columns
`{:("","Column-I","","Column-II"),(A,"Hygrophytes",1,"problems of water loss"),(B,"mesophytes",2,"excess water in guttation"),(C,"xerophytes",3,"luxuriant vegeratative growth"):}`

Options

A. `{:(A,B,C),(2,3,1):}`
B. `{:(A,B,C),(2,1,3):}`
C. `{:(A,B,C),(1,2,3):}`
D. `{:(A,B,C),(1,3,2):}`

Answer

To solve the matching question, we need to understand the characteristics of each type of plant mentioned in Column-I and then match them with the appropriate descriptions in Column-II.

### Step-by-Step Solution:

1. **Identify Hygrophytes**:
- Hygrophytes are plants that thrive in moist and shady environments. They have adaptations that allow them to manage excess water.
- **Match**: They expel excess water through structures like stomata or hydathodes, which corresponds to "excess water in guttation."
- **Conclusion**: Hygrophytes (A) match with 2 (excess water in guttation).

2. **Identify Mesophytes**:
- Mesophytes are plants that grow in moderate conditions, where water availability is neither too much nor too little. They have well-developed root systems and foliage.
- **Match**: Their growth is characterized by luxuriant vegetative growth due to favorable conditions.
- **Conclusion**: Mesophytes (B) match with 3 (luxuriant vegetative growth).

3. **Identify Xerophytes**:
- Xerophytes are plants adapted to arid environments and have mechanisms to minimize water loss. They face problems related to water scarcity.
- **Match**: They are associated with "problems of water loss."
- **Conclusion**: Xerophytes (C) match with 1 (problems of water loss).

### Final Matches:
- A (Hygrophytes) → 2 (excess water in guttation)
- B (Mesophytes) → 3 (luxuriant vegetative growth)
- C (Xerophytes) → 1 (problems of water loss)

### Answer Summary:
- A → 2
- B → 3
- C → 1
