C - Payload is not modified, but attributes and variables are not sent to the private flow

In MuleSoft, when an outbound HTTP request is made within a Mule flow, it can impact the attributes of the Mule event in the following ways: Message Payload: The outbound HTTP request usually replaces the current message payload with the response received from the HTTP endpoint. So, the original payload that was in the Mule event before the HTTP request is overwritten by the response data. Message Attributes: The HTTP response often brings along its own set of attributes. These attributes may include HTTP headers (e.g., Content-Type, Status Code) and other metadata related to the HTTP response. These attributes can be accessed in your flow after the HTTP request. Exception Payload: If an error occurs during the HTTP request (e.g., a network error, timeout, or HTTP error response), Mule may set an exception payload in the event. You can handle this exception in your flow, possibly by using an error-handler component or flow. So the answer would be C.

C - I agree with C

In Mule event....Mule message [Payload + Attributes] , Variables.... Attribute values updates....wen any request...
