### Step-by-Step Solution:

1. **Identify the Key Features**:
- The question specifies four characteristics:
- Hard shell
- Muscular body
- Ommatophores
- Foot

2. **Understanding Ommatophores**:
- Ommatophores are tentacle-like structures that have eyes, and they are characteristic of organisms in the phylum Mollusca.

3. **Evaluate the Options**:
- **Option A: Periplaneta (Cockroach)**:
- This organism belongs to the phylum Arthropoda. It does not have a hard shell or ommatophores. Therefore, this option is incorrect.
- **Option B: Limulus (Horseshoe Crab)**:
- Limulus is also an arthropod and lacks the features of a mollusk, including ommatophores. This option is incorrect.
- **Option C: Spila**:
- This is a genus of snails that belong to the class Gastropoda within the phylum Mollusca. Snails typically have a hard shell, a muscular body, and ommatophores.
- **Option D: Tortoise**:
- Tortoises belong to the phylum Chordata and do have a hard shell, but they do not have ommatophores. Thus, this option is also incorrect.

4. **Conclusion**:
- After evaluating all the options, the only organism that possesses all the specified features (hard shell, muscular body, ommatophores, and foot) is **Option C: Spila**.

### Final Answer:
The correct answer is **Option C: Spila**.
