According to the AWS Shared Responsibility Model, the responsibility for scheduling maintenance, patches, and other updates for an Aurora database lies with the customer. This includes managing the maintenance windows, scheduling updates, and applying patches to the Aurora database.
I agree the answer is C as per the Document here:
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_UpgradeDBInstance.Maintenance.html
If an update is available, you can take one of the actions:
If the maintenance value is next window, defer the maintenance items by choosing Defer upgrade from Actions. You can't defer a maintenance action if it has already started.
Apply the maintenance items immediately.
Schedule the maintenance items to start during your next maintenance window.
Take no action.

according to this link, AWS is in charge of the maintenance
