What does the DELETE HTTP method accomplish?

• A. Creates a resource
• B. Retrieves a resource
• C. Updates a resource
• D. Removes a resource

Answer: (D)

The DELETE HTTP method is specifically designed to remove a resource from a server. When a DELETE request is sent, it indicates that the client wants to delete the identified resource, as specified by the URI (Uniform Resource Identifier) in the request. Upon successful execution of the DELETE method, the server is expected to remove the resource and typically responds with a status code indicating the result of that operation.

In general web service and RESTful API design, each HTTP method corresponds to a specific CRUD (Create, Read, Update, Delete) operation. While the other methods like POST, GET, and PUT are used for creating, retrieving, and updating resources respectively, DELETE solely focuses on removal. This is why the choice indicating that it "removes a resource" is the accurate description of the DELETE method's functionality.
