The correct option is NFS share.

NFS share is a network file system that can be mounted by multiple Pods on different worker nodes and it supports the Kubernetes access mode ReadWriteMany so multiple consumers can read and write the same filesystem concurrently.

GCE Persistent Disk is block storage that is typically attached to a single node for read and write access and it does not provide a POSIX shared filesystem across nodes in standard Kubernetes setups, so it does not meet the requirement for a common filesystem accessible by Pods on different nodes.

HostPath mounts a directory from the node running the Pod and it is node local so Pods on other nodes cannot access the same host path concurrently, which makes it unsuitable for a cluster wide shared filesystem.

Local Persistent Volume binds storage to a specific node and exposes raw local disks or directories to Pods on that node only, so it cannot serve as a shared filesystem across multiple worker nodes even though it is useful for high performance local storage.
