Which approach should you take?

Flowlogistic is rolling out their real-time inventory tracking system. The tracking devices will all send package-tracking messages, which will now go to a single Google Cloud Pub/Sub topic instead of the Apache Kafka cluster. A subscriber application will then process the messages for real-time reporting and store them in Google BigQuery for historical analysis. You want to ensure the package data can be analyzed over time.

Which approach should you take?
A . Attach the timestamp on each message in the Cloud Pub/Sub subscriber application as they are received.
B . Attach the timestamp and Package ID on the outbound message from each publisher device as they are sent to Clod Pub/Sub.
C . Use the NOW () function in BigQuery to record the event’s time.
D . Use the automatically generated timestamp from Cloud Pub/Sub to order the data.
