Options

A. Halophyte-Wheat
B. Xerophyte-Mustard
C. Gerophyte-Tomato
D. Hydrophyte-Pistia

Answer

To solve the question of finding the correct match among the given options, we will analyze each option based on the definitions of the plant types mentioned.

### Step-by-Step Solution:

1. **Understanding Halophytes**:
- Halophytes are plants that thrive in high salinity environments, such as salt marshes or coastal areas.
- **Option 1**: Halophyte - Weed
- Weeds are generally not halophytes as they do not typically grow in high salt concentrations. Therefore, this match is **incorrect**.

2. **Understanding Xerophytes**:
- Xerophytes are plants adapted to survive in environments with very little water, such as deserts.
- **Option 2**: Xerophyte - Mustard
- Mustard plants require a moderate amount of water and are not adapted to extremely dry conditions. Thus, this match is **incorrect**.

3. **Analyzing Tomato**:
- **Option 3**: Xerophyte - Tomato
- Tomatoes require a significant amount of water for growth and are not classified as xerophytes. Hence, this match is also **incorrect**.

4. **Understanding Hydrophytes**:
- Hydrophytes are plants that grow in or near water, often submerged or floating.
- **Option 4**: Hydrophyte - Pistia
- Pistia, commonly known as water lettuce, is indeed a hydrophyte as it grows in aquatic environments. Therefore, this match is **correct**.

### Conclusion:
The only correct match from the options provided is:
- **Hydrophyte - Pistia**.
