Match column I with column II and select the correct option from the given codes.
`{:("Column I","Column II"),("Division of nucleus",(i)"Interphase"),("Division of cytoplasm",(ii)"Cytokinesis"),("DNA replication",(iii)"Syncytium"),("Karyokinesis not followed by cytokinesis",(iv)"Karyokinesis"):}`

Options

A. a.ii,b.iv,c.i,d.iii
B. a.iv,b.ii,c.i,d.iii
C. a.iv,b.ii,c.iii,d.i
D. a.iii,b.ii,c.iv,d.i

Answer

To solve the matching question between Column I and Column II, we will analyze each term in Column I and find its corresponding match in Column II.

### Step-by-Step Solution:

1. **Division of Nucleus**:
- This process is known as **Karyokinesis**. It refers to the division of the nucleus during cell division.
- **Match**: Division of Nucleus → Karyokinesis (iv)

2. **Division of Cytoplasm**:
- This process is called **Cytokinesis**. It is the final step in cell division where the cytoplasm is divided into two daughter cells.
- **Match**: Division of Cytoplasm → Cytokinesis (ii)

3. **DNA Replication**:
- DNA replication occurs during the **Interphase** of the cell cycle. This is the phase where the cell prepares for division by duplicating its DNA.
- **Match**: DNA Replication → Interphase (i)

4. **Karyokinesis not followed by Cytokinesis**:
- When karyokinesis occurs without cytokinesis, it leads to the formation of a **Syncytium**, which is a multinucleated cell.
- **Match**: Karyokinesis not followed by Cytokinesis → Syncytium (iii)

### Summary of Matches:
- Division of Nucleus → Karyokinesis (iv)
- Division of Cytoplasm → Cytokinesis (ii)
- DNA Replication → Interphase (i)
- Karyokinesis not followed by Cytokinesis → Syncytium (iii)

### Final Matching:
- A → iv (Division of Nucleus → Karyokinesis)
- B → ii (Division of Cytoplasm → Cytokinesis)
- C → i (DNA Replication → Interphase)
- D → iii (Karyokinesis not followed by Cytokinesis → Syncytium)

### Correct Option:
The correct option based on the matches is **B**: A4, B2, C1, D3.
