Match column I with column II and select the correct option from the given codes.
`{:("Column I","Column II"),("Chromosomes move to equator",(i)"Pachytene"),("Centromere splits and ",(ii)"Zygotene"),("Pairing between homologous chromosomes",(iii)"Anaphase"),("Crossing over between homologous chromosomes",(iv)"Metaphase"):}`

Options

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

Answer

To solve the problem of matching Column I with Column II, we will analyze each statement in Column I and identify the corresponding phase in Column II.

### Step-by-Step Solution:

1. **Chromosomes move to equator**:
- This event occurs during **Metaphase**. In this phase, chromosomes align at the cell's equatorial plane in preparation for separation.
- **Match**: Chromosomes move to equator → (iv) Metaphase

2. **Centromere splits**:
- The splitting of the centromere occurs during **Anaphase**. This is when sister chromatids are pulled apart to opposite poles of the cell.
- **Match**: Centromere splits → (iii) Anaphase

3. **Pairing between homologous chromosomes**:
- This pairing occurs during **Zygotene**, which is a stage of Prophase I in meiosis where homologous chromosomes come together and begin to pair.
- **Match**: Pairing between homologous chromosomes → (ii) Zygotene

4. **Crossing over between homologous chromosomes**:
- Crossing over occurs during **Pachytene**, which is another stage of Prophase I in meiosis where homologous chromosomes exchange genetic material.
- **Match**: Crossing over between homologous chromosomes → (i) Pachytene

### Final Matches:
- Chromosomes move to equator → (iv) Metaphase
- Centromere splits → (iii) Anaphase
- Pairing between homologous chromosomes → (ii) Zygotene
- Crossing over between homologous chromosomes → (i) Pachytene

### Summary of Matches:
- 1 → iv
- 2 → iii
- 3 → ii
- 4 → i

### Correct Option:
Based on the matches, the correct option is **C** (1 → iv, 2 → iii, 3 → ii, 4 → i).
