Which of the following is the SLOWEST method of restoring data from backup media?

The SLOWEST method of restoring data from backup media is an incremental backup. This is because an incremental backup is a type of backup that only copies the files that have been created or modified since the previous backup, whether it was a full or an incremental backup. An incremental backup makes the restoration process slower, as it requires restoring multiple backups in a specific order and sequence, starting from the last full backup and then applying each incremental backup until the desired point in time is reached. The other options are not methods of restoring data from backup media that are slower than an incremental backup, but rather different types of backup procedures that copy files based on different criteria, such as monthly backup (A), full backup (B), or differential backup C.
