Which HTTP method is typically used to retrieve a resource representation from a server?

• A. HEAD
• B. GET
• C. TRACE
• D. POST

Answer: (B)

Retrieving a resource representation from a server is done with the GET method. GET asks the server to transfer the current state of the resource, and the response body typically contains the representation you want (such as HTML, JSON, or XML). It’s designed to be safe and idempotent, meaning it should not cause side effects and repeated requests should yield the same result, which makes it ideal for read-only operations. The other HTTP methods have different purposes: HEAD fetches just the headers, useful for checking metadata without the body; TRACE echoes back the request for diagnostic purposes; POST is used to submit data to the server to create or modify resources, which can change server state.
