Match the following column I with column II .
`{:("Column - I","Column - II"),("A - Metaphase - II","1. Centromere with 2 kinetochores"),("B. Anaphase -I","2. Disjunction"),("C. Mitosis","3. Synapse"),("D. Zygotene","4. Plectonemic coiling"):}`

Options

A. `{:(A,B,C,D),(1,2,4,5):}`
B. `{:(A,B,C,D),(1,2,4,2):}`
C. `{:(A,B,C,D),(2,3,1,4):}`
D. `{:(A,B,C,D),(4,1,3,2):}`

Answer

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

### Step-by-Step Solution:

1. **Identify Column I Terms**:
- A: Metaphase - II
- B: Anaphase - I
- C: Mitosis
- D: Zygotene

2. **Analyze Metaphase - II**:
- In Metaphase II, the chromosomes align at the metaphase plate, and each chromosome is attached to spindle fibers at the centromere, which has two kinetochores (one for each sister chromatid).
- **Match**: A - 1 (Centromere with 2 kinetochores)

3. **Analyze Anaphase - I**:
- During Anaphase I, homologous chromosomes are separated and pulled to opposite poles of the cell. This separation is known as disjunction.
- **Match**: B - 2 (Disjunction)

4. **Analyze Mitosis**:
- Mitosis involves the division of a cell into two identical daughter cells. During this process, plectonemic coiling of chromosomes is observed, which refers to the coiling of DNA into a compact structure.
- **Match**: C - 4 (Plectonemic coiling)

5. **Analyze Zygotene**:
- Zygotene is a stage in prophase I of meiosis where homologous chromosomes come together and synapse, forming tetrads.
- **Match**: D - 3 (Synapse)

### Final Matches:
- A - 1 (Metaphase - II → Centromere with 2 kinetochores)
- B - 2 (Anaphase - I → Disjunction)
- C - 4 (Mitosis → Plectonemic coiling)
- D - 3 (Zygotene → Synapse)

### Summary of Matches:
- A → 1
- B → 2
- C → 4
- D → 3
