A company needs to securely dispose of data stored on optical discs. Which of the following is the MOST effective method to accomplish this task?

Degaussing is used for magnetic media (like hard drives, tapes) to neutralize magnetic fields, and it is ineffective on optical discs.

Low-level formatting applies to magnetic storage devices to re-write the physical sectors; it is not applicable or effective for optical discs.

Recycling optical discs without prior secure destruction does not remove the data and poses a security risk.

Shredding physically destroys the optical disc by breaking it into small, unreadable fragments, making it the most effective method for rendering the data irretrievable. This ensures complete data sanitization and meets security requirements for sensitive information stored on such media.
