The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Thalloid Structure**: The term "thalloid" refers to a plant body that does not have distinct leaves, stems, or roots. Instead, it has a simple structure that resembles a thallus. 2. **Identifying Plant Groups**: The question presents four options: Phaneria, Sphagnum, Salvinia, and Marchantia. We need to determine which of these has a thalloid body. 3. **Analyzing Each Option**: - **Phaneria**: This plant does not have a thalloid structure; it has more complex features. - **Sphagnum**: This is a type of moss and does not exhibit a thalloid body; it has distinct structures. - **Salvinia**: This is a pteridophyte (a type of fern) and also does not have a thalloid structure. - **Marchantia**: This is a liverwort, which is a type of bryophyte known for having a thalloid body. 4. **Conclusion**: Among the options provided, Marchantia is the only plant that has a thalloid body. It belongs to the class Hepaticopsida within the division Bryophyta. 5. **Final Answer**: The plant body is thalloid in Marchantia. ---
