Which of the following is a correct match between organism and its respective respiratory structure?

Options

A. Prawn — Tracheal system
B. King crab — Book lungs
C. Scorpion — Gills
D. Centipede — Tracheal system

Answer

To determine the correct match between organisms and their respective respiratory structures, let's analyze each option step by step:

1. **Prawn and Tracheal System**:
- Prawns are aquatic organisms that primarily use gills for respiration. Gills are specialized structures that allow them to extract oxygen from water. Therefore, this match is incorrect.

**Hint**: Remember that aquatic animals typically use gills for respiration.

2. **King Crab and Book Gills**:
- King crabs, scientifically known as Limulus, possess book gills, which are flat, leaf-like structures that facilitate gas exchange in aquatic environments. This match is correct.

**Hint**: Book gills are specific to certain aquatic arthropods, including some crabs.

3. **Scorpion and Book Lungs**:
- Scorpions have book lungs, which are structures that resemble pages of a book and are adapted for respiration in terrestrial environments. This match is also correct.

**Hint**: Book lungs are found in terrestrial arthropods like scorpions.

4. **Centipede and Tracheal System**:
- Centipedes have a well-developed tracheal system that allows for efficient gas exchange directly with the environment. This match is correct.

**Hint**: The tracheal system is a characteristic feature of many terrestrial arthropods, including centipedes.

After analyzing all options, we find that the correct matches are:
- King Crab with Book Gills
- Scorpion with Book Lungs
- Centipede with Tracheal System

However, since the question asks for a single correct match, the best answer is **Centipede with Tracheal System**, as it is explicitly mentioned in the question.

**Final Answer**: The correct match is **Centipede with Tracheal System**.
