Which type of information is commonly exempt under "national security"?

• A. Details about public services
• B. Information that could harm national defense or security interests
• C. Data related to environmental impact
• D. Personal data of citizens

Answer: (B)

The type of information that is commonly exempt under "national security" is information that could harm national defense or security interests. This includes sensitive details related to military operations, intelligence gathering, and any other data that, if disclosed, could jeopardize the safety and security of a nation. Protecting this type of information is essential to ensure that adversaries do not gain access to knowledge that could undermine a country's ability to defend itself or conduct operations effectively.

Other types of information mentioned, such as details about public services, data related to environmental impact, and personal data of citizens, do not inherently relate to national security. They may have their own exemptions or considerations under different legal frameworks but are not prioritized within the context of protecting national interests in the same way that national defense and security information is.
