At what point will the Cognizant Security Office (CSO) permit the release of classified material?

The correct answer is based on the requirement that both governments must approve security arrangements before classified material can be released. This ensures that there is mutual agreement on how the classified information will be handled, protected, and utilized under the terms of the disclosure. The approval process is critical for maintaining the integrity and security of sensitive information, which is especially important in international relations and intelligence sharing.

When both governments have approved the security arrangements, it establishes a formal cooperation framework that allows for safe exchanges of classified material. This approval also typically involves validating that the receiving entity has appropriate security measures in place to protect the classified information, thereby mitigating the risk of unauthorized access or disclosure.

The other options do not meet the stringent requirements set forth for disclosing classified materials. For instance, leveraging the timing of transportation, resolving internal audits, or responding solely to requests from allied nations does not necessarily ensure that proper security protocols and agreements are in place. Therefore, the necessity of both governments' approval underscores the importance of established diplomatic and security protocols in handling classified information.
