• A. To create a new resource
• B. To delete an existing resource
• C. To develop or overwrite a resource
• D. To read a resource

Answer: (C)

The primary use of the PUT method in a REST API is to develop or overwrite a resource. PUT is typically employed for updates or the creation of a resource at a specific URI. When a client sends a PUT request, it usually includes the representation of the resource in the body of the request. If the resource already exists at the provided URI, the server will replace it with the new representation. If it does not exist, the server can create a new resource with that URI. This makes PUT an idempotent operation, meaning that multiple identical requests will result in the same state on the server, reinforcing the idea of developing or overwriting a resource as needed.
