The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Retractile Claws**: Retractile claws are specialized claws that can be extended or retracted. This ability allows animals to keep their claws protected when not in use, which is beneficial for various activities such as hunting and climbing. 2. **Mechanism of Retraction**: The retraction of claws is achieved by a mechanism involving the pivoting of the end bone of the toe. This allows the claws to be pulled back into a sheath, protecting them from wear and tear. 3. **Identifying Animals with Retractile Claws**: The question asks which animals possess retractile claws. The primary group known for having retractile claws is the cat family (Felidae). 4. **Evaluating Other Options**: - **Dogs**: Dogs have dew claws that are not fully retractile. They are useful for gripping and running but do not retract completely. - **Foxes**: Similar to dogs, foxes also do not have fully retractile claws. - **Hyenas**: Although they may resemble dogs, hyenas do not have retractile claws either. 5. **Conclusion**: Based on the evaluation, the only group that possesses fully retractile claws is the cat family. Therefore, the correct answer is that claws are retractile in cats. **Final Answer**: Claws are retractile in cats. ---
