A. Antheridiophore
B. Archegoniophore
C. Both A and B
D. Tassel.

Answer

To solve the question regarding the dioecious plant Marchantia and where it develops its sex organs, follow these steps:

### Step-by-Step Solution:

1. **Understand the Term Dioecious**:
- A dioecious plant is one that has distinct male and female individuals. This means that male and female reproductive organs are found on separate plants.

**Hint**: Remember that "dioecious" indicates separate sexes in plants.

2. **Identify the Plant in Question**:
- The plant mentioned is Marchantia, which is a type of liverwort. It is known for having a distinct male and female form.

**Hint**: Focus on the characteristics of Marchantia as a dioecious plant.

3. **Know the Male and Female Structures**:
- In Marchantia, the male reproductive structure is called the **Antheridiophore**, which produces male gametes (sperm).
- The female reproductive structure is called the **Archegoniophore**, which produces female gametes (eggs).

**Hint**: Associate "Antheridiophore" with male and "Archegoniophore" with female.

4. **Analyze the Options Provided**:
- A. Antheridiophore (male)
- B. Archegoniophore (female)
- C. Both A and B (indicating both male and female structures)
- D. Tessel (not relevant to Marchantia's reproductive structures)

**Hint**: Look for the option that includes both male and female reproductive structures.

5. **Select the Correct Answer**:
- Since Marchantia develops sex organs on both the Antheridiophore (male) and Archegoniophore (female), the correct answer is **C. Both A and B**.

**Hint**: Confirm that both structures are necessary for the reproduction of dioecious plants.

### Final Answer:
The dioecious plant Marchantia develops sex organs on **C. Both A and B** (Antheridiophore and Archegoniophore).
