The correct REST Django expression to retrieve events with the label "notable" that are in the "new" status is using the container endpoint, as containers are used to store events and associated data in Splunk SOAR. The expression correctly filters the events by label (_filter_label="notable") and status (_filter_status="new"), ensuring only notable events that are still in the "new" status are selected.
A and D reference the wrong endpoints (event and notable respectively), which do not align with the container-based model used in Splunk SOAR for storing and filtering events.
B is incorrect due to the use of _filter_name instead of _filter_label, which is not a valid filter in this context.
