• C) 403 Forbidden
        
• D) 404 Not Found
    

Correct Answer: B) 401 Unauthorized

Explanation:

The HTTP 401 Unauthorized client error status response code indicates that the request has not been completed because it lacks valid authentication credentials for the target resource.

Breakdown of Options:

        
• 400 Bad Request: Indicates that the server cannot process the request due to perceived client-side syntax errors, invalid routing, or malformed data framing.
        
• 401 Unauthorized: Correct. Indicates authentication is required and has either failed or not yet been provided.
        
• 403 Forbidden: The client identity is recognized, but the client does not have access permissions for the resource (authorization failure).
        
• 404 Not Found: The origin server did not find a current representation for the target resource.
