Mathc the column I with column II and select the correct option from the given codes.
`{:("Column I","Column II"),("Plant virus",(i)"Kuru disease"),("Animal virus",(ii)"Potato spindle tuber"),("Viroids",(iii)"Polio"),("Prions",(iv)"Tobacco mosaic"):}`

Options

A. iv,iii,ii,i
B. i,ii,iii,iv
C. iii,iv,i,ii
D. ii,iii,iv,i

Explanation

To solve the question of matching Column I with Column II, we will analyze each item in Column I and find the corresponding item in Column II based on the characteristics and examples of each category.

### Step-by-Step Solution:

1. **Identify Plant Viruses**:
- Plant viruses are primarily RNA viruses.
- A well-known example is the **Tobacco Mosaic Virus**.
- **Match**: Plant virus → (iv) Tobacco Mosaic.

2. **Identify Animal Viruses**:
- Animal viruses can include various types, including those that cause diseases in humans and animals.
- A notable example is **Polio**, which is caused by the poliovirus.
- **Match**: Animal virus → (iii) Polio.

3. **Identify Viroids**:
- Viroids are smaller than viruses and are known to cause specific plant diseases.
- A classic example is the **Potato Spindle Tuber** disease.
- **Match**: Viroids → (ii) Potato Spindle Tuber.

4. **Identify Prions**:
- Prions are misfolded proteins that cause neurodegenerative diseases.
- An example of a disease caused by prions is **Kuru disease**, which affects the brain.
- **Match**: Prions → (i) Kuru disease.

### Final Matching:
- Plant virus → (iv) Tobacco Mosaic
- Animal virus → (iii) Polio
- Viroids → (ii) Potato Spindle Tuber
- Prions → (i) Kuru disease

### Correct Option:
The correct option based on the matches is:
- (iv), (iii), (ii), (i)
