The correct answer is the storage account with standard access tier. This type of storage account is designed to accommodate various data workloads and allows for different redundancy options. When the storage account is set to standard access, it means it is suitable for scenarios where data access patterns are infrequent and can benefit from increased durability options like zone-redundant storage (ZRS).

Zone-redundant storage is primarily aimed at providing high availability and resiliency against regional failures by ensuring that data is replicated across multiple zones within a region. The standard tier supports the conversion to ZRS since it offers options for object storage with sufficient performance characteristics and is well integrated into the Azure ecosystem.

In contrast, a storage account with premium performance is optimized for low-latency access and generally uses locally redundant storage (LRS) or geo-redundant storage (GRS) rather than ZRS. The storage accounts with the Cool access tier are intended for data that is infrequently accessed and may have different replication settings that do not support ZRS. Lastly, standard performance storage with a Hot access tier is typically better suited for workloads with high-access demands and also aligns differently with redundancy configurations than what ZRS offers.

Thus, the standard access tier storage account is
