Which statement best describes HTTP GET semantics?

• A. Retrieves data without changing server state.
• B. Sends data to server to create a new resource.
• C. Deletes a resource.
• D. Requires a request body.

Answer: (A)

HTTP GET is a safe, read-only operation that retrieves a representation of a resource without changing anything on the server. Because of this, GET is idempotent—repeating the same request should yield the same result and not alter data. In practice, any parameters are sent in the URL as path segments or query parameters, not in the body, and a request body is not required for GET (and many servers ignore bodies on GET). The other statements describe actions that create or delete resources or imply a required request body, which don’t match GET’s purpose.
