Respiratory system plays an important role of enabling gas exchange and supply of oxygen to the animals. Although, the basic mechanism of the system remains same , animals display variation in their respiratory system. In the following columns match the animals with their organ for respiration.
`{:(,"Animal",," Respiratory"),(1,"Kangaroo",P,"Moist cuticle"),(2,"Pomfret ",Q,"Lungs"),(3,"Cockroach",R,"Gills"),(4,"Earthworm",S,"Tracheal tubes"):}`

Options

A. 1-Q , 2-P ,3-S , 4-R
B. 1-Q , 2-R ,3-S , 4-P
C. 1-Q , 2-R ,3-P , 4-S
D. 1-Q , 2-P ,3-R, 4-S

Answer

To solve the question, we need to match each animal with its corresponding respiratory organ. Let's analyze each animal and its respiratory system step by step.

### Step 1: Identify the respiratory organ of the Kangaroo
- **Kangaroo**: Kangaroos are marsupial mammals that primarily use **lungs** for respiration.
- **Match**: Kangaroo - Q (Lungs)

### Step 2: Identify the respiratory organ of the Pomfret
- **Pomfret**: Pomfret is a type of fish, and fish use **gills** to extract oxygen from water.
- **Match**: Pomfret - R (Gills)

### Step 3: Identify the respiratory organ of the Cockroach
- **Cockroach**: Cockroaches belong to the phylum Arthropoda and have a unique respiratory system that consists of **tracheal tubes**. These tubes transport air directly to the tissues.
- **Match**: Cockroach - S (Tracheal tubes)

### Step 4: Identify the respiratory organ of the Earthworm
- **Earthworm**: Earthworms belong to the phylum Annelida and breathe through their **moist cuticle** (skin), which allows gas exchange directly with the environment.
- **Match**: Earthworm - P (Moist cuticle)

### Final Matching Summary
1. Kangaroo - Q (Lungs)
2. Pomfret - R (Gills)
3. Cockroach - S (Tracheal tubes)
4. Earthworm - P (Moist cuticle)

### Conclusion
The correct matches are:
- Kangaroo → Q (Lungs)
- Pomfret → R (Gills)
- Cockroach → S (Tracheal tubes)
- Earthworm → P (Moist cuticle)

Thus, the answer is:
- 1 → Q
- 2 → R
- 3 → S
- 4 → P
