Match the columns and identify the correct option
`{:("Column -I ","Column-II"),("Thylakoids","(i) Disc-shaped sacs in golgi appartus"),("Cristae","(ii) Condensed structure of DNA"),("Cisternae","(iii) Flat membranous sacs in stroma"),("Chromatin","(iv) Infoldings in mitochondria"):}`

Options

A. `{:(,(1),(2),(3),(4)), (,(iv),(iii), (i), (ii)):}`
B. `{:(,(1),(2),(3),(4)), (,(iii),(iv), (i), (ii)):}`
C. `{:(,(1),(2),(3),(4)), (,(iii),(i), (iv), (ii)):}`
D. `{:(,(1),(2),(3),(4)), (,(iii),(iv), (ii), (i)):}`

Answer

To solve the matching question, we will analyze each item in Column-I and find its corresponding match in Column-II based on the definitions provided.

### Step-by-Step Solution:

1. **Thylakoids**:
- Thylakoids are flat membranous sacs found in the chloroplasts. They are arranged in a coin-like pattern and are involved in the photosynthesis process.
- **Match**: (iii) Flat membranous sacs in stroma.

2. **Cristae**:
- Cristae are the infoldings of the inner membrane of mitochondria. They increase the surface area for chemical reactions.
- **Match**: (iv) Infoldings in mitochondria.

3. **Cisternae**:
- Cisternae are disc-shaped sacs found in the Golgi apparatus. They are involved in the modification and transport of proteins.
- **Match**: (i) Disc-shaped sacs in Golgi apparatus.

4. **Chromatin**:
- Chromatin is the condensed structure of DNA found in the nucleus of a cell. It is responsible for packaging DNA into a smaller volume to fit in the nucleus.
- **Match**: (ii) Condensed structure of DNA.

### Final Matching:
- Thylakoids → (iii) Flat membranous sacs in stroma
- Cristae → (iv) Infoldings in mitochondria
- Cisternae → (i) Disc-shaped sacs in Golgi apparatus
- Chromatin → (ii) Condensed structure of DNA

### Correct Option:
The correct option based on the matches is:
- 1 → 3
- 2 → 4
- 3 → 1
- 4 → 2

Thus, the answer is **Option 2**.
