- Grandfather

Explanation:

In the given scenario, the 'grandfather backup rotation strategy' is employed to have the backup of the audiotape files. This is because the entire process is segregated into three distinct sections; daily backup that keeps the track of all the files recorded every day. It is followed by weekly storage of the audio files after the week wraps up in order to save it for future usage. Lastly, 'monthly' media is backed up in order to ensure that no data is left to be backed up that might be required later. This promotes a quicker, easier, yet complete strategy for backing up the desired data files in the systems. Hence, 'grandfather-son-rotation strategy' is the correct answer.
