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

Options

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

Answer

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

### Step 1: Analyze the first option
- **Housefly, Butterfly, Taxa, Fly, Silverfish**:
- All these organisms belong to the **phylum Arthropoda**.
- Within Arthropoda, they are classified under the **class Insecta**.
- Silverfish, while often considered a pest, is indeed an insect and falls under Insecta.
- **Conclusion**: This option is correctly matched.

### Step 2: Analyze the second option
- **Ant eater (specifically spiny ant eater), Sea Urchin, Sea Cucumber**:
- Sea Urchin and Sea Cucumber belong to the **phylum Echinodermata**.
- However, the spiny ant eater is a mammal and belongs to the **phylum Mammalia**.
- **Conclusion**: This option is incorrectly matched.

### Step 3: Analyze the third option
- **Flying Fish, Cuttlefish, Silverfish**:
- Flying Fish belongs to the **class Actinopterygii** within the phylum **Chordata** (not Pisces, which is an outdated term).
- Cuttlefish belongs to the **phylum Mollusca** and is part of the class Cephalopoda.
- Silverfish belongs to the **phylum Arthropoda** and class Insecta.
- **Conclusion**: This option is incorrectly matched.

### Step 4: Analyze the fourth option
- **Centipede, Millipede, Spider, Scorpion**:
- All these organisms belong to the **phylum Arthropoda**.
- However, they do not belong to the class Insecta. Centipedes belong to the class Chilopoda, millipedes belong to the class Diplopoda, and spiders and scorpions belong to the class Arachnida.
- **Conclusion**: This option is incorrectly matched.

### Final Conclusion
The only correctly matched option is the **first option**: Housefly, Butterfly, Taxa, Fly, Silverfish all belong to the class Insecta under the phylum Arthropoda.
