Answer

To solve the question "Rhizoids containing sporophytic plants are characteristic of:", we will analyze the options provided and identify the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Rhizoids**: These are root-like structures that anchor the plant and help in absorption.
- **Sporophytic Plants**: The sporophyte is the diploid phase in the life cycle of plants that produces spores.

- **Psychodophyta**: This is not a commonly recognized group in plant taxonomy.
- **Psilopsida**: This group includes whisk ferns, which have a unique structure where the sporophyte is rootless and has rhizoids.

3. **Identifying the Correct Group**:
- Among the options, **Psilopsida** is known for having rhizoids associated with its sporophytes. The rhizomes in this group bear rhizoids that perform root-like functions.

4. **Conclusion**:
- Therefore, the correct answer to the question is **Psilopsida**.
