C.
Geo-redundant storage (GRS)

How to approach this question
Look for the redundancy options that include 'Geo' (geography).
Full Answer
Geo-redundant storage (GRS), Geo-zone-redundant storage (GZRS)
Geo-redundant storage (GRS) and Geo-zone-redundant storage (GZRS) both copy your data to a secondary region hundreds of miles away from the primary region. This protects your data even if the entire primary region goes offline.
Common mistakes
Selecting ZRS. ZRS protects against a datacenter failure, but if the whole region floods, ZRS data is lost.
