`{:("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 between Column I and Column II, we will analyze each item in Column I and find the corresponding event in Column II.

### Step-by-Step Solution:

1. **Metaphase II (A)**:
- In Metaphase II of meiosis, the chromosomes align at the equatorial plane of the cell. Each chromosome consists of two sister chromatids. The key feature of Metaphase II is that each centromere has two kinetochores, one for each sister chromatid.
- **Match**: A - 1 (Centromere with 2 kinetochores).

2. **Anaphase I (B)**:
- In Anaphase I of meiosis, homologous chromosomes are separated and pulled towards opposite poles of the cell. This process is known as disjunction, where the pairs of chromosomes are separated.
- **Match**: B - 2 (Disjunction).

3. **Mitosis (C)**:
- Mitosis is also known as equational division, where the chromosome number remains the same in the daughter cells as in the parent cell. During this process, the chromosomes are tightly coiled, and this coiling is referred to as plectonemic coiling.
- **Match**: C - 4 (Plectonemic coiling).

4. **Zygotene (D)**:
- Zygotene is a stage in prophase I of meiosis where homologous chromosomes begin to pair and undergo synapsis, forming tetrads. This is the stage where synapsis occurs.
- **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
