D. A-I, B-ii, C-iv, D-iii

Answer

To solve the matching question regarding animals and their respective respiratory organs, we will go through each animal and identify the correct respiratory organ based on biological knowledge.

### Step-by-Step Solution:

1. **Identify the respiratory organ of Earthworm**:
- Earthworms perform respiration through their skin, specifically via a moist cuticle. This process is known as cutaneous respiration.
- **Match**: Earthworm → (i) Moist cuticle.

2. **Identify the respiratory organ of Aquatic Arthropods**:
- Aquatic arthropods, such as crabs and shrimp, primarily use gills for respiration. Gills are specialized organs that extract oxygen from water.
- **Match**: Aquatic Arthropods → (ii) Gills.

3. **Identify the respiratory organ of Fishes**:
- Fishes also use gills to extract oxygen from water. Gills are adapted to facilitate gas exchange in aquatic environments.
- **Match**: Fishes → (ii) Gills.

4. **Identify the respiratory organ of Birds/Reptiles**:
- Birds and reptiles primarily use lungs for respiration. Lungs are adapted for breathing air and are crucial for their survival.
- **Match**: Birds/Reptiles → (iii) Lungs.

5. **Identify the respiratory organ of Insects (Trachea)**:
- Insects, including many arthropods, use a tracheal system for respiration. This system consists of a network of tubes (tracheae) that deliver oxygen directly to tissues.
- **Match**: Insects → (iv) Trachea.

### Final Matching:
- Earthworm → (i) Moist cuticle
- Aquatic Arthropods → (ii) Gills
- Fishes → (ii) Gills
- Birds/Reptiles → (iii) Lungs
- Insects → (iv) Trachea

### Summary of Correct Matches:
- Earthworm: (i) Moist cuticle
- Aquatic Arthropods: (ii) Gills
- Fishes: (ii) Gills
- Birds/Reptiles: (iii) Lungs
- Insects: (iv) Trachea
