Explanation

Authentication is the process of proving you are who you claim to be. A username (user ID) establishes identity (identification), and the password is the secret factor used to prove that identity - together they constitute authentication. Identification alone is just claiming an identity without proof. Authorization (Option A) is what happens after authentication - determining what resources you are permitted to access. Auditing (Option B) refers to tracking and logging user actions after they are authenticated and authorized. The combination of credential + secret = authentication.
