You are tasked with ensuring data resiliency for a critical stateful application deployed on GKE. Which storage and backup options will you use?

*Explanation:* The correct option is A. GCE persistent disks with Regional PD and Cloud Storage for backups. GCE persistent disks offer durability, and when used as Regional PDs, they offer high availability. Cloud Storage is an ideal option for backups. Options B, C, D, and E lack either the resiliency required for stateful applications or are not suitable for GKE environments.
