Answer

To determine which of the given Pteridophytes belong to the class Pteropsida, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Pteridophytes**:
- Pteridophytes are vascular plants that are divided into different classes. The main classes include:
- Coelopsida
- Lycopsida
- Sphenopsida
- Pteropsida

2. **Analyze Each Option**:
- **Option 1: Equisetum and Psilotum**
- Equisetum belongs to the class Sphenopsida.
- Psilotum belongs to the class Psilotopsida.
- Therefore, this option does not belong to Pteropsida.

- **Option 2: Lycopodium and Adiantum**
- Lycopodium belongs to the class Lycopsida.
- Adiantum belongs to the class Pteropsida.
- Since Lycopodium is not part of Pteropsida, this option is incorrect.

- **Option 3: Selaginella and Terris**
- Selaginella belongs to the class Lycopsida.
- Terris (which is likely referring to "Ferns" or "Terrestrial ferns") belongs to the class Pteropsida.
- Since Selaginella is not part of Pteropsida, this option is also incorrect.

- **Option 4: Terris and Adiantum**
- Terris belongs to the class Pteropsida.
- Adiantum also belongs to the class Pteropsida.
- Both plants in this option belong to Pteropsida, making this the correct answer.

3. **Conclusion**:
- The plants that belong to the class Pteropsida from the given options are **Terris and Adiantum**.

### Final Answer:
