### Step 1: Understand the Question
The question asks for the taxonomic rank that corresponds to roundworms. The options provided are genus, family, phylum, or class.

### Step 2: Identify the Taxonomic Classification of Roundworms
Roundworms are commonly known as nematodes. In biological classification, nematodes belong to a specific taxonomic rank.

### Step 3: Determine the Correct Taxonomic Rank
- **Genus**: This is a rank that groups species that are closely related. Roundworms are not classified at this level.
- **Family**: This is a higher rank than genus, grouping several genera. Roundworms do not represent a family.
- **Class**: This is a higher taxonomic rank than family but still does not encompass the entire group of roundworms.
- **Phylum**: This is a major taxonomic rank that groups together organisms with similar characteristics. Roundworms are classified under the phylum Nematoda.
