Refer to the exhibit. Which set of API requests must be executed by a Webex Teams bot after receiving webhook callback to process messages in a room and reply with a new message back to the same room?

Choice A incorrectly uses a singular '/message' endpoint that does not exist in the Webex Teams API; the correct endpoint is '/messages' (plural).

PUT /messages is incorrect because PUT updates an existing resource; replying to a room requires creating a new message with POST, and the mentionedPeople filter is unnecessary for a basic room reply.

Choice C uses both an incorrect singular endpoint '/message' and PUT instead of POST, neither of which is valid for sending a new reply message in Webex Teams.

After receiving a webhook callback, the bot retrieves the room's messages using GET /messages with the roomId query parameter to read the triggering message, then sends a reply by creating a new message resource with POST /messages including the roomId and text in the request body.
