This is clearly SGrid and MC – so A and C are correct.
This is not a good question. Not clear. C is correct for sure. But the snapshots in its basic meaning – frozen state of Active File System – is local. So it goes down with the site. SnapMirror would be different thing. So I would say the second must be StorageGrid. Just by eliminating the incorrect.
BC.
this is for storagegrid explanation:
While placing replicated copies on different Storage Nodes in a single storage pool works well for deployments that have only one site, using a single storage pool does not provide site-loss protection in deployments that have multiple sites. Because the system uses any available nodes in the storage pool when it places the replicated copies, it might place all copies of some objects within only one of the sites.
Snapshot copies can be mounted and access in case of failure
StorageGRID is for Cloud Tiering. The Data Protection function of Information Lifecycle Management (ILM) whilst do protect data, but does not address business continuity.
SnapMirror would address DR to provide immediate access to mirrored data in event the source goes down. However since this option is not there. I am unsure of the answer, but C is definitely correct.
in the 4 options, only MC and storageGRID have multi-site fault- tolerance.
