All of the following are steps in derivative classification EXCEPT:

A. Marking the information to show its classified status.

B. Making the initial determination that information requires protection against unauthorized disclosure in the interest of national security.

C. Determining whether information has been classified previously.

D. Carrying forward that determination into new material.

Answer:- B. Making the initial determination that information requires protection against unauthorized disclosure in the interest of national security.

The practice of producing new classified information based on previously existing classified information is known as derivative classification. Information that is classified is divided into levels according to its level of sensitivity and potential harm. Additionally, its unapproved release would endanger national security. These levels often include classifications such as “secret,” “confidential,” and “top secret.”

This process involves applying the same or a lower classification level to the new information, ensuring that its sensitivity is appropriately safeguarded.
