Answer

To solve the question of matching the distinguishing features based on chromosomal appearance with the corresponding stages of meiosis, we will analyze each feature and determine its correct stage.

### Step-by-Step Solution:

1. **Identify the Features and Stages**:
- Features (List I):
- (A) Terminalized chiasmata
- (B) Exchange of segments of chromatids
- (C) Synapsis of homologous chromosomes
- (D) Appearance of chiasmata
- Stages (List II):
- 1. Pachytene
- 2. Zygotene
- 3. Diakinesis
- 4. Leptotene
- 5. Diplotene

2. **Match Feature (A) Terminalized chiasmata**:
- Terminalized chiasmata refers to the movement of chiasmata towards the ends of the chromosomes, which occurs during **Diakinesis**.
- **Match**: (A) → 3

3. **Match Feature (B) Exchange of segments of chromatids**:
- The exchange of segments of chromatids is known as crossing over, which occurs during the **Pachytene** stage.
- **Match**: (B) → 1

4. **Match Feature (C) Synapsis of homologous chromosomes**:
- The synapsis of homologous chromosomes occurs during the **Zygotene** stage, where homologous chromosomes pair up.
- **Match**: (C) → 2

5. **Match Feature (D) Appearance of chiasmata**:
- The appearance of chiasmata is typically observed during the **Diplotene** stage, where the paired chromosomes start to separate but are still connected at the chiasmata.
- **Match**: (D) → 5

### Final Matches:
- (A) → 3 (Diakinesis)
- (B) → 1 (Pachytene)
- (C) → 2 (Zygotene)
- (D) → 5 (Diplotene)

### Conclusion:
The correct matching is:
- A - 3
- B - 1
- C - 2
- D - 5
