The goal is to pull (fetch) messages from a subscription and acknowledge them.
The gcloud pubsub subscriptions **pull** command retrieves messages from a specified subscription.
The --auto-ack flag instructs the command to automatically acknowledge the messages after they are successfully retrieved, combining the two required actions into one command.
'Pulls one or more messages from the specified subscription. To acknowledge the pulled messages, use the --auto-ack flag.'

Wait, can you really auto-ack with that command? Sounds risky!

I’m confused about the difference between pulling and seeking. I guess I need to double-check what each command does before answering.

I practiced a question like this, and I feel like pulling messages is definitely the way to go. So, C seems like the best choice.

I'm not entirely sure, but I remember something about using the seek command in a similar question. Could that be relevant here?

I think option C sounds right because it mentions pulling messages and auto-acknowledging them, which is what we need to do.
