Select the correct option from the following:

Options

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

Answer

To solve the matching question regarding meiosis, we need to analyze each term in Column-I and find the corresponding term in Column-II. Let's go through each of them step by step.

### Step-by-Step Solution:

1. **Zygotene**:
- During the zygotene stage of meiosis, homologous chromosomes begin to pair up. This process is known as **synapsis**.
- **Match**: Zygotene → (iv) Synapsis.

2. **Pachytene**:
- In the pachytene stage, the paired homologous chromosomes undergo a process called **crossing over**, where genetic material is exchanged between them.
- **Match**: Pachytene → (iii) Crossing over.

3. **Diplotene**:
- The diplotene stage is characterized by the chromosomes becoming more visible and forming an X-like structure. This is also where the chiasmata (the points of crossing over) become apparent.
- **Match**: Diplotene → (ii) Chiasmata.

4. **Diakinesis**:
- In diakinesis, the final preparations for meiosis occur, and the chiasmata move towards the ends of the chromosomes, a process known as **terminalization**.
- **Match**: Diakinesis → (i) Terminalization.

### Final Matches:
- 1. Zygotene → (iv) Synapsis
- 2. Pachytene → (iii) Crossing over
- 3. Diplotene → (ii) Chiasmata
- 4. Diakinesis → (i) Terminalization

### Therefore, the correct option is:
- 4th → Zygotene
- 3rd → Pachytene
- 2nd → Diplotene
- 1st → Diakinesis
