Who is responsible for the initial determination to classify information?

The correct choice is Original Classification Authorities because they hold the designated responsibility for the initial classification of information. These authorities are individuals who have been granted the legal power to classify information based on national security interests. They assess whether the information meets specific criteria defined in executive orders and regulations, determining if it needs protection from unauthorized disclosure.

This classification process is crucial, as it establishes the parameters for handling sensitive information and ensures that it is safeguarded appropriately. Original Classification Authorities must base their decisions on established guidelines, considering the potential impact on national security if the information were to be disclosed.

Other roles, such as derivative classifiers or administrative personnel, do not have the same level of authority to make initial classification decisions. Their responsibilities usually involve handling information that has already been classified or implementing classification decisions made by Original Classification Authorities.
