Which one belongs to same taxonomic group ?

Options

A. Papilio, Xenopsylla, Musca
B. Starfish, Cat Fish, Cray Fish
C. Tapeworm, Hookworm, Silkworm
D. Physalia, solen, Toredo.

Answer

To determine which group of organisms belongs to the same taxonomic group, we will analyze the options provided:

### Step 1: Analyze Option A
- **Organisms**: Papilio, Xenopsila, Musca
- **Taxonomic Group**: These organisms belong to the phylum **Arthropoda** (not Orthopoda, which is a typo in the transcript). They are all insects and share characteristics such as jointed appendages and an exoskeleton.

### Step 2: Analyze Option B
- **Organisms**: Starfish, Catfish, Crayfish
- **Taxonomic Group**:
- **Starfish** belongs to phylum **Echinodermata**.
- **Catfish** belongs to phylum **Chordata**.
- **Crayfish** belongs to phylum **Arthropoda**.
- Conclusion: These organisms do not belong to the same taxonomic group.

### Step 3: Analyze Option C
- **Organisms**: Tapeworm, Hookworm, Silkworm
- **Taxonomic Group**:
- **Tapeworm** belongs to phylum **Platyhelminthes** (flatworms).
- **Hookworm** belongs to phylum **Nematoda** (roundworms).
- **Silkworm** belongs to phylum **Arthropoda**.
- Conclusion: These organisms do not belong to the same taxonomic group.

### Step 4: Analyze Option D
- **Organisms**: Physalia, Solan, Toredo
- **Taxonomic Group**:
- **Physalia** (Portuguese man o' war) belongs to phylum **Cnidaria**.
- **Solan** (a type of mollusk) belongs to phylum **Mollusca**.
- **Toredo** (shipworm) also belongs to phylum **Mollusca**.
- Conclusion: These organisms do not belong to the same taxonomic group as Physalia is from Cnidaria, while Solan and Toredo are from Mollusca.

### Final Conclusion
From the analysis, the organisms that belong to the same taxonomic group are:
- **Option A**: Papilio, Xenopsila, Musca (all belong to phylum **Arthropoda**).
