Answer

To determine which of the given options represents a "Phylum," we need to analyze each option based on the taxonomical hierarchy.

### Step-by-Step Solution:

1. **Understanding Taxonomical Hierarchy**:
- The taxonomical hierarchy is structured as follows: Kingdom > Phylum > Class > Order > Family > Genus > Species.
- In this hierarchy, "Phylum" is a major taxonomic rank that groups together organisms based on shared characteristics.

2. **Analyzing the Options**:
- **Mammalia**: This is a class within the animal kingdom that includes all mammals. Therefore, it does not represent a phylum.

- **Solanum**: This is a genus that includes various species of plants, such as potatoes and tomatoes. It does not represent a phylum.
- **Carnivora**: This is an order within the class Mammalia that includes carnivorous mammals like cats and dogs. It does not represent a phylum.

3. **Identifying the Correct Answer**:
- Among the options provided, **Caudata** is the only one that represents a phylum.

### Final Answer:
The option that represents "Phylum" is **Caudata**.
