The most secure method for storing backup tapes is?

Storing backups in a locked desk drawer offers minimal security and no protection against building-wide disasters.

Storing backups in the same building, even on a different floor, still leaves them vulnerable to the same localized disasters (e.g., fire, flood) that could affect the primary data center.

While a cool, dry climate is important for tape preservation, simply specifying this without off-site storage does not address disaster recovery or security from localized threats.

Storing backup tapes off-site in a climate-controlled area provides protection against physical disasters that could affect the primary data center, such as fire, flood, or theft, ensuring business continuity. Climate control also prevents the degradation of tape media due to extreme temperatures or humidity, preserving data integrity over time.

Storing backups in a fireproof safe inside the data center still subjects them to other localized disasters that could affect the entire data center, such as major power outages or theft, and doesn't offer geographic redundancy.

This is incorrect because off-site, climate-controlled storage is indeed the most secure and recommended method.
