Malocophily is observed in

Options

A. Ruppia
B. Zostera
C. Lemma
D. Bignonia.

Answer

**Step-by-Step Solution:**

1. **Understanding Malacophily**:
- Malacophily refers to a type of cross-pollination where the pollinating agents are snails or slugs.

2. **Identifying the Options**:
- The options given are Rupia, Zoosterra, Lama, and Bignonia.

3. **Analyzing Each Option**:
- **Rupia**: This is a hydrophyte, meaning it grows in water. Pollination in Rupia occurs through water, which is termed hydrophily. Therefore, Rupia is not associated with malacophily.
- **Zoosterra**: Similar to Rupia, Zoosterra is also a hydrophyte and relies on water for pollination (hydrophily). Thus, it is also not associated with malacophily.
- **Lema**: This plant is known to exhibit malacophily, as it is specifically pollinated by snails or slugs. Hence, this option is a strong candidate for the correct answer.
- **Bignonia**: Pollination in Bignonia occurs through birds, which is known as ornithophily. Therefore, this option is also incorrect in relation to malacophily.

4. **Conclusion**:
- After analyzing all the options, the only plant that shows malacophily is **Lema**. Therefore, the correct answer is **C. Lema**.
