Answer

To answer the question "Plant body of liverworts is," we need to analyze the options provided and understand the characteristics of liverworts.

### Step-by-Step Solution:

1. **Understanding Liverworts**:
- Liverworts are small, non-vascular plants that reproduce via spores. They belong to the group of bryophytes.

2. **Types of Liverworts**:
- Liverworts can be classified into two main types: thalloid liverworts and leafy liverworts.
- Thalloid liverworts have a flat, lobed structure resembling a liver, which is where the name "liverwort" comes from.
- Leafy liverworts have a structure that resembles leaves.

3. **Analyzing the Options**:
- **Option 1: Thalloid in Porella**:
- Porella is a genus of liverworts that has a flat, dorsi-ventral (two-sided) and folios (leaf-like) body. Therefore, this option is incorrect as Porella does not have a thalloid body.
- **Option 2: Thalloid in Marchantia**:
- Marchantia is a well-known genus of liverworts that has a thallus-like body, which is flat and dorsi-ventrally differentiated. This option is correct.
- **Option 3: Leafy in Marchantia**:
- Marchantia is characterized by its thallus-like structure, not a leafy structure. Hence, this option is incorrect.
- **Option 4: More than one option is correct**:
- Since only the second option is correct, this option is also incorrect.

4. **Conclusion**:
- The correct answer is that the plant body of liverworts is thalloid in Marchantia.

### Final Answer:
The plant body of liverworts is thalloid in Marchantia.
