The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Mollusca**: Mollusca is a diverse group of invertebrates that typically have a soft body and may or may not possess a hard shell. 2. **Function of the Shell**: The shell in mollusks serves primarily as a protective structure, made mostly of calcium carbonate. It helps protect the soft body from predators and environmental hazards. 3. **Identifying Shell-less Mollusks**: While many mollusks have shells, some do not. Key examples of mollusks without shells include octopuses, squids, and cuttlefish. 4. **Listing Examples**: - **Octopus**: A well-known mollusk that lacks a shell. - **Squid**: Another example of a shell-less mollusk. - **Cuttlefish**: Similar to squids, cuttlefish also do not have an external shell. 5. **Conclusion**: Based on the examples provided, the answer to the question "The mollusk without a shell is" can be concluded as **octopus**. 6. **Final Answer**: Therefore, the correct option is **octopus**. ---
