C can be correct now as NearSync can support application-consistent snapshots from AOS 5.20 onwards. However, minutely snapshots are not application-consistent but hourly snapshots are.

A is correct C. is incorrect + NearSync does not support application-consistent snapshots + NearSync replication schedules of less than 15 minutes do not support self-service restore. https://portal.nutanix.com/page/documents/details?targetId=Prism-Element-Data-Protection-Guide-v6_6:wc-cluster-dr-nearsync-limitations-r.html
