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 problem of matching animals with their respective respiratory organs, we can follow these steps:

### Step 1: Identify the Respiratory Organ for Each Animal

1. **Kangaroo**: Kangaroos are marsupial mammals and possess lungs for respiration. Therefore, we match Kangaroo with **Lungs** (Q).

2. **Pomfret**: Pomfret is a type of fish, and fish use **Gills** (R) to extract oxygen from water. So, we match Pomfret with Gills.

3. **Cockroach**: Cockroaches are insects and do not have lungs. Instead, they breathe through a system of **Tracheal tubes** (S) that transport air directly to their tissues. Thus, we match Cockroach with Tracheal tubes.

4. **Earthworm**: Earthworms respire through their **Moist cuticle** (P), which allows gas exchange through their skin. Therefore, we match Earthworm with Moist cuticle.

### Step 2: Compile the Matches

Now we can summarize the matches:
- **Kangaroo** → **Lungs** (Q)
- **Pomfret** → **Gills** (R)
- **Cockroach** → **Tracheal tubes** (S)
- **Earthworm** → **Moist cuticle** (P)

### Final Matching

Based on the above analysis, the correct matches are:
1. Kangaroo - Q (Lungs)
2. Pomfret - R (Gills)
3. Cockroach - S (Tracheal tubes)
4. Earthworm - P (Moist cuticle)

### Conclusion

The correct answer is:
- 1 → Q
- 2 → R
- 3 → S
- 4 → P
