Which is one of the three categories of a classified message?

• A. Self
• B. Working with others
• C. Performance
• D. Priority

Answer: (A)

The main idea here is that classified messages are organized by who the content is for or who must act on it. One category is Self, which means the message is intended for the author’s own use or action—it's information you need to act on yourself or keep for your personal records, not something you’re expected to distribute widely. This makes Self a natural, clear category because it designates the message as a personal responsibility or reference item.

So why this is the best fit? Because the question asks for a category that identifies the intended recipient, and Self directly points to the sender as the primary audience. The other common categories describe situations involving others or the urgency level, but they don’t define the message as being for the author’s own action or records the same way Self does.
