Which of the following represents correct match of feature with the given set of animals ?

Options

A. `{:("Feature","Animals"),("Respiratory system "," - Coakroach Tapeworm,Starfish "):}`
B. `{:("Feature","Animals"),("Bilateral symmetry","- Hydra,Tapeworm Sea urchin "):}`
C. `{:("Feature","Animals"),("Jointed appendages","- Prawn,CentipedeGrasshoper" "):}`
D. `{:("Feature","Animals"),("Metameric segmentation","- Earthworm ,Leech,Liverfluke "):}`

Answer

To determine which of the following represents the correct match of features with the given set of animals, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the Features and Animals**:
- We have three features to analyze: respiratory system, bilateral symmetry, and jointed appendages.
- The animals mentioned are cockroach, tapeworm, starfish, hydra, prawn, centipede, grasshopper, earthworm, leech, and liver fluke.

2. **Analyze the First Feature: Respiratory System**:
- **Cockroach**: Respiration occurs through spiracles (correct).
- **Tapeworm**: Lacks a respiratory system (incorrect).
- **Starfish**: Respiration occurs through tube feet and papulae (correct).
- **Conclusion**: This option is incorrect because tapeworm does not have a respiratory system.

3. **Analyze the Second Feature: Bilateral Symmetry**:
- **Hydra**: Exhibits radial symmetry (incorrect).
- **Tapeworm**: Exhibits bilateral symmetry (correct).
- **Sea Urchin**: Exhibits radial symmetry (incorrect).
- **Conclusion**: This option is incorrect because hydra and sea urchin do not have bilateral symmetry.

4. **Analyze the Third Feature: Jointed Appendages**:
- **Prawn**: Has jointed appendages (correct).
- **Centipede**: Has jointed appendages (correct).
- **Grasshopper**: Has jointed appendages (correct).
- **Conclusion**: This option is correct as all three animals belong to the phylum Arthropoda, which is characterized by jointed appendages.

5. **Analyze the Fourth Feature: Metameric Segmentation**:
- **Earthworm**: Exhibits metameric segmentation (correct).
- **Leech**: Exhibits metameric segmentation (correct).
- **Liver Fluke**: Does not exhibit metameric segmentation; it belongs to the phylum Platyhelminthes (incorrect).
- **Conclusion**: This option is incorrect because liver fluke does not show metameric segmentation.

### Final Conclusion:
The only correct match of feature with the given set of animals is the third option: **Jointed Appendages with Prawn, Centipede, and Grasshopper**.
