Match the columns and select the correct option from the following.
`{:(,"Column I",,"Column II"),((A),"Wheat rust ",(I),"Edible"),((B),"Antibiotics",(II),"Puccinia"),((C),"Mushroom",(III),"Sac fungi"),((D),"Ascomycetes",(IV),"Penicillium"):}`

Options

A. A - I, B - II, C - IV, D - III
B. A - I, B - IV, C - II, D - III
C. A - II, B - IV, C - I, D - III
D. A - II, B - IV, C - III, D - I

Answer

To solve the matching question, we need to pair the items in Column I with the correct items in Column II based on their definitions or characteristics.

### Step-by-Step Solution:

1. **Identify Wheat Rust**:
- Wheat rust is a fungal disease caused by the genus **Puccinia**. Specifically, **Puccinia triticina** is known for affecting wheat.
- **Match**: A (Wheat rust) → II (Puccinia)

2. **Identify Antibiotics**:
- Antibiotics are substances used to kill bacteria and are often derived from fungi. One well-known antibiotic is **Penicillium**, which is used to produce penicillin.
- **Match**: B (Antibiotics) → IV (Penicillium)

3. **Identify Mushroom**:
- Mushrooms are a type of fungi that are often edible. The common edible mushroom is **Agaricus bisporus**.
- **Match**: C (Mushroom) → I (Edible)

4. **Identify Ascomycetes**:
- Ascomycetes are a class of fungi known as **sac fungi** because they produce spores in a sac-like structure called an ascus.
- **Match**: D (Ascomycetes) → III (Sac fungi)

### Final Matches:
- A → II (Wheat rust → Puccinia)
- B → IV (Antibiotics → Penicillium)
- C → I (Mushroom → Edible)
- D → III (Ascomycetes → Sac fungi)

### Conclusion:
The correct option for the matching is:
- A - II
- B - IV
- C - I
- D - III
