Selected Answer: D
D is correct because optical disks can be shredded when the disk is no longer needed. Degaussing only applies to the HDD.

No, because unlike HDDs, optical disks are not magnetic. So shredding it would work, breaking in half can work too.

I go with D. Degaussing is a method used to erase data from magnetic media, such as hard drives. So it is not effective for optical discs.
