The places where animals receive protection are called animal sanctuaries.

Explanation:
Animal sanctuaries are designated areas where animals are provided with protection and care. These sanctuaries are established with the aim of preserving and conserving various species of animals, especially those that are endangered or in need of special care.

Key Points:
Here are some key points to understand why animal sanctuaries are the correct answer:
- National Parks: While national parks also provide some level of protection to animals, their main focus is on preserving the natural environment and promoting tourism. Animal sanctuaries, on the other hand, specifically focus on the well-being and protection of animals.
- Rock shelters: Rock shelters are natural formations that may provide temporary refuge to some animals, but they do not encompass the concept of organized protection and care for animals.
- Animal sanctuaries: These sanctuaries are dedicated to providing a safe haven for animals, ensuring their well-being, and often rehabilitating animals that have been rescued from harmful situations such as illegal wildlife trade, poaching, or abusive environments.
- Conservation efforts: Animal sanctuaries play a crucial role in conservation efforts by providing a protected environment for animals to live and thrive, allowing them to breed, and in some cases, reintroducing them into their natural habitats.
- Specialized care: Animal sanctuaries often have trained staff and facilities to cater to the specific needs of different species. They provide appropriate diets, medical care, and enrichment activities to ensure the physical and mental well-being of the animals.
- Educational purposes: Many animal sanctuaries also serve as educational centers, raising awareness about the importance of wildlife conservation, the threats animals face, and the need for their protection.

Conclusion:
Animal sanctuaries are designated areas that provide protection, care, and specialized attention to animals. They play a vital role in conservation efforts and help ensure the well-being of various species.
