I guess this should be C. Notifications are sent through Webhooks. https://www.cisco.com/c/dam/en/us/td/docs/telepresence/endpoint/ce98/collaboration-endpoint-software-api-reference-guide-ce98.pdf

Question not clearly worded but I agree. When using xcommands via SSH, everything is done... well, in the SSH session, you get notification on the CLI. The same goes for serial. Websockets it's a full duplex connection, so over the same connection of a request, the endpoint can send notifications. When using HTTP/HTTPS the only way to get a feedback on an event is via Webhooks, which is a separate connection.
