Answer: C

Explanation:

According to CompTIA A+ Core 2 objectives, a full backup stored off-site provides the greatest protection against data loss in the event of a ransomware attack or other data disaster. By storing the backup in a separate physical location, it is less likely to be affected by the same event that could cause data loss on the original system. Cold storage is a term used for data archiving, which typically refers to a long-term storage solution that is used for retaining data that is infrequently accessed, but still needs to be kept for regulatory or compliance reasons.
