Which redundancy option replicates data across regions and allows read access to the secondary?

RA-GRS (Read-Access Geo-Redundant Storage) is the correct option because it replicates data across two geographically separate Azure regions and provides read access to the data in the secondary region. This allows for high availability and disaster recovery, as applications can read from the secondary region if the primary region becomes unavailable. LRS (Locally Redundant Storage) replicates data within a single data center. ZRS (Zone-Redundant Storage) replicates data across three Azure availability zones within a single region. GRS (Geo-Redundant Storage) replicates data across two geographically separate Azure regions but does not provide read access to the secondary region directly; it's primarily for disaster recovery where failover is required to access the secondary.
