C. Wolffia and Utricularia
D. All are correct.

Answer

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Rootless**: This term refers to plants that do not possess roots. Roots are typically used for anchoring the plant and for the absorption of water and nutrients from the soil.
- **Angiosperms**: These are flowering plants that produce seeds enclosed within a fruit.

2. **Identifying Rootless Angiosperms**:
- While most angiosperms have roots, there are exceptions, particularly among aquatic plants and some small terrestrial plants. These plants have adapted to their environments in such a way that they do not require roots for their survival.

3. **Examples of Rootless Angiosperms**:
- Some notable examples include:
- **Utricularia** (commonly known as bladderwort): This is an aquatic plant that captures small organisms using specialized bladders.
- **Wolffia**: This is the smallest flowering plant and is also rootless.
- Other examples mentioned include **Lugubrigia** and **Eutrichilia**.

4. **Conclusion**:
- The correct answer to the question "Rootless angiosperms are" is that they include plants like Utricularia and Wolffia, which do not have roots and have adapted to their environments.
