What does extending classification involve?

Extending classification involves lengthening the duration of how long certain information is classified. This process is typically necessary when the original reasons for classifying the information remain valid, and there is a continued need to protect it from unauthorized disclosure. By extending the classification, the organization ensures that sensitive information stays protected beyond its initial classification timeline. This is crucial in maintaining national security or protecting sensitive data that could compromise operations if disclosed.

The other potential answers do not accurately represent the concept of extending classification. Making information available to the public denotes declassification, not extension. Changing the classification authority involves administrative adjustments regarding who has the power to classify information but does not directly relate to the duration of the classification. Reducing the classification level implies a downgrade, which is contrary to the notion of extending the classification duration.
