Options

A. Chara and Marchantia
B. Maize and Carica
C. Papaya and date palm
D. Marchantia and fucus

Answer

To solve the question regarding the female sex organs (gametangia) known as oogonium and archegonium, we will analyze the options given and identify the correct pair.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- Oogonium is a female gametangium found in certain algae and fungi.
- Archegonium is a female gametangium found in bryophytes (like mosses) and some other plants.

2. **Analyzing the Options**:
- **Option A: Kara and Marcancia**
- Kara (Chara) is a green algae, and its female reproductive organ is called oogonium.
- Marcancia (Marchantia) is a liverwort, and its female reproductive organ is called archegonium.
- **Option B: Maize and Carica**
- Maize (Zea mays) is an angiosperm, and it does not have oogonium or archegonium.
- Carica (Papaya) is also an angiosperm, and it does not have these structures.
- **Option C: Papaya and Date Palm**
- Both are angiosperms and do not possess oogonium or archegonium.
- **Option D: Marcancia and Fucous**
- Marcancia is a liverwort with archegonium, but Fucous (Fucus) is a brown algae with a different type of gametangium called megasporangium.

3. **Identifying the Correct Answer**:
- From the analysis, we see that **Kara (Chara)** has oogonium and **Marcancia (Marchantia)** has archegonium.
- Therefore, the correct answer is **Option A: Kara and Marcancia**.

### Final Answer:
**Kara and Marcancia** are the organisms where oogonium and archegonium are the respective female sex organs.
