Answer Description

A differential backup is the best option because it saves all changes made since the last full backup, making it quicker to restore the most recent data in case of failure. Full backups are taken weekly to ensure complete data restoration, while differential backups ensure changes made during the week are protected efficiently. Incremental backups are less efficient in this scenario because they save changes made since the last backup (full or incremental), making restoration time longer as each increment has to be processed. A synthetic backup requires merging previous backups, which might not provide the most updated data quickly.
