Which one is the species?

Options

A. Carnivora
B. Canis
C. familiaris
D. Canis familiaris

Answer

To determine which option represents a species, we need to analyze each of the given options step by step.

### Step 1: Understand the Terms
- **Order**: A higher taxonomic category that includes one or more families. For example, "Carnivora" is an order that includes families such as Felidae (cats) and Canidae (dogs).
- **Genus**: A taxonomic category that is one rank above species. It groups together species that are closely related. For example, "Canis" is the genus that includes dogs, wolves, and other similar animals.
- **Species**: The most specific level of classification, which identifies a single type of organism. It is often represented by a two-part name (binomial nomenclature), such as "Canis familiaris" for domestic dogs.

### Step 2: Analyze the Options
1. **Carnivora**: This is an order, not a species.
2. **Canis**: This is a genus, not a species.
3. **Familiaries**: This term seems to be a misspelling or misinterpretation. It does not represent a recognized taxonomic category.
4. **Canis familiaris**: This is the scientific name for the domestic dog, where "Canis" is the genus and "familiaris" is the species.

### Step 3: Identify the Species
From the analysis above, the only option that represents a species is **Canis familiaris**.

### Final Answer
The species among the options provided is **Canis familiaris**.
