  C: Use watermarks and timestamps to capture the lagged data. Watermarks are a way to indicate that some data may still be in transit and not yet processed. By setting a watermark, you can define a time period during which Dataflow will continue to accept late or out-of-order data and incorporate it into your processing. This allows you to maintain a predictable time period for processing while still allowing for some flexibility in the arrival of data. Timestamps, on the other hand, are used to order events correctly, even if they arrive out of order. By assigning timestamps to each event, you can ensure that they are processed in the correct order, even if they don't arrive in that order.
