To solve this question, the user needs to have knowledge of data retention policies and best practices for managing defective media.

Option A: Using the defective media for overwriting current logs is not recommended. The data on the defective media is potentially corrupted or lost, and using it for overwriting current logs can result in further data loss or inconsistency.

Option B: This is the correct answer. Informing stakeholders and degaussing the media is the best approach for managing defective media. Degaussing the media involves exposing it to a magnetic field to erase all data stored on it. This is a secure and effective way to dispose of defective media.

Option C: Keeping the defective media safely and securely in a fireproof safe may seem like a good idea, but it is not an effective way to manage defective media. The data on the defective media is still potentially corrupted or lost, and there is no guarantee that it will remain secure in the safe.

Option D: Formatting the media is not recommended. Formatting may not be effective in erasing all data, and it may also overwrite any remaining data on the media, making it difficult or impossible to recover.

Therefore, the correct answer is:

The Answer is: B. Inform stakeholders and degauss the media.
