Which feature indicates classified information under the FOIA?

• A. Information about national security
• B. Trade secrets
• C. Privileged litigation information
• D. All of the above

Answer: (D)

The feature that indicates classified information under the Freedom of Information Act (FOIA) encompasses various types of sensitive information, including national security information, trade secrets, and privileged litigation information. The FOIA allows for the withholding of information that could compromise national security, which helps protect sensitive government operations and intelligence activities.

Trade secrets and privileged information are also protected under FOIA. Trade secrets refer to proprietary information that provides a business advantage over competitors; revealing such secrets can harm a company's economic interests. Privileged litigation information pertains to legal proceedings and may include attorney-client communications or work product that the law protects from disclosure.

Therefore, all these types of information are classified under specific provisions of the FOIA, justifying the selection of the option that encompasses all of them as the correct answer. This illustrates the breadth of protection afforded by FOIA concerning sensitive information.
