Explanation

Palo Alto Networks App-ID uses a dependency model where some applications require a 'base' application to function. 'facebook-chat' (B) is the specific application being used for chat, but it runs over 'facebook-base' (C), which handles the foundational Facebook web infrastructure (login, session management, etc.). Without explicitly allowing facebook-base, the underlying traffic required for Facebook-chat to function will be blocked. 'facebook' (A) is a broader identifier and not the specific dependency required. 'facebook-email' (D) is a separate Facebook sub-application unrelated to chat functionality.
