A. B. C. D.A.
The incremental backup method usually resets the archive bit on the files after they have been backed up.
An Incremental Backup will backup all the files that have changed since the last Full Backup (the first time it is run after a full backup was previously completed) or after an Incremental Backup (for the second backup and subsequent backups) and sets the archive bit to 0.This type of backup take less time during the backup phase but it will take more time to restore.
The other answers are all incorrect choices.
The following backup types also exists: Full Backup - All data are backed up.
The archive bit is cleared, which means that it is set to 0
Differential Backup - Backup the files that have been modified since the last Full Backup.
The archive bit does not change.
Take more time while the backup phase is performed and take less time to restore.

The backup method that usually resets the archive bit on the files after they have been backed up is the Incremental backup method.
Incremental backups are a type of backup that only backs up the data that has changed or been added since the last backup was performed. The archive bit is a file attribute that is used to indicate whether a file has been modified since the last backup. When a file is modified, the archive bit is set to indicate that the file has changed and needs to be backed up again.
When an incremental backup is performed, it only backs up the files that have the archive bit set, indicating that they have been modified since the last backup. Once the backup is complete, the archive bit is reset for each file that was backed up, so that the next incremental backup will only back up the files that have been modified since the previous incremental backup.
Differential backups, on the other hand, back up all the changes made since the last full backup. The archive bit is not reset after a differential backup, so the next differential backup will back up all the changes made since the last full backup.
Partial backups and tape backups are not standard backup methods and are not commonly used. Partial backups may refer to backing up only certain files or directories, while tape backups refer to the use of magnetic tape as a backup medium. Neither of these methods is specifically associated with resetting the archive bit.
