Which HTTP header indicates what content types the client can accept in responses?

• A. Content-Type
• B. Accept
• C. Server
• D. User-Agent

Answer: (B)

Content negotiation in HTTP uses the Accept header to indicate which content types the client can process in responses. It lets the server choose a representation that the client can handle, and it can include quality values to express preference among types. If no acceptable type is available, the server may respond with an error such as Not Acceptable. The other headers aren’t about what content types the client can accept: Content-Type describes the media type of the body being sent or received, Server identifies the server software, and User-Agent describes the client application.
