Based on the storage accounts in the provided table, which storage account can be converted to zone-redundant storage (ZRS) replication?

storage1 can be converted to ZRS because it uses Standard general-purpose v2, which supports ZRS. storage2 uses Premium block blobs, which does not support ZRS. storage3 uses Standard FileStorage, which also does not support ZRS. ZRS is a replication option that synchronously copies your data across three Azure availability zones within the primary region, providing high availability and durability. It's crucial to select the correct storage account type and performance tier to utilize ZRS.
