Which of the following are correctly matched with respect to their taxonomic classification?

Options

A. (a) House fly, butterfly, tsetsefly, silverfish - Insecta
B. (b) Spiny anteater, sea urchin, sea cucumber - Echinodermata
C. (c) Flying fish, cuttlefish, silverfish -Pisces
D. (d) Centipede, millipede, spider, scorpion - Insecta

Answer

To determine which of the given options are correctly matched with respect to their taxonomic classification, we can analyze each option step by step:

1. **Identify the Organisms and Their Classes:**
- The question provides several options, each containing a list of organisms. We need to identify the taxonomic classification of each organism in the options.

2. **Analyze Option A:**
- **Housefly** (Musca domestica) - Class Insecta
- **Butterfly** (Order Lepidoptera) - Class Insecta
- **Sassafly** (likely a typo for "sawfly") - Class Insecta
- **Silverfish** (Lepisma saccharinum) - Class Insecta
- Conclusion: All organisms in Option A belong to Class Insecta. Therefore, this option is correctly matched.

3. **Analyze Option B:**
- **Spiny Anteater** (Echidna) - Class Mammalia (Phylum Chordata)
- **Sea Urchin** - Class Echinoidea (Phylum Echinodermata)
- **Sea Cucumber** - Class Holothuroidea (Phylum Echinodermata)
- Conclusion: The spiny anteater does not belong to Echinodermata; hence, this option is incorrectly matched.

4. **Analyze Option C:**
- **Flying Fish** - Class Actinopterygii (Phylum Chordata)
- **Cuttlefish** - Class Cephalopoda (Phylum Mollusca)
- **Silverfish** - Class Insecta (Phylum Arthropoda)
- Conclusion: Silverfish does not belong to Pisces; thus, this option is incorrectly matched.

5. **Analyze Option D:**
- **Centipedes** - Class Chilopoda (Phylum Arthropoda)
- **Millipedes** - Class Diplopoda (Phylum Arthropoda)
- **Spider** - Class Arachnida (Phylum Arthropoda)
- **Scorpion** - Class Arachnida (Phylum Arthropoda)
- Conclusion: None of these belong to Class Insecta; hence, this option is incorrectly matched.

6. **Final Conclusion:**
- The only option that is correctly matched with respect to their taxonomic classification is **Option A**.

### Summary of the Correct Answer:
The correct answer is **Option A**: Housefly, Butterfly, Sassafly, and Silverfish all belong to Class Insecta.
