Correct answer: Authentication identifies and verifies a user who is attempting to access a system, and authorization controls the tasks the user performs..
Why this is the answer
Authentication is the process of verifying a user's identity, typically through credentials like a username and password, to confirm they are who they claim to be. Authorization, on the other hand, determines what an authenticated user is permitted to do or access within the system. It defines the specific permissions and restrictions for that user. The incorrect options confuse these distinct roles. For example, authorization does not log activities (that's accounting), nor does it handle communication with user databases (that's part of the authentication process). Similarly, authentication is more than just identifying; it's about verification.
