Explanation

RADIUS (Remote Authentication Dial-In User Service) is an AAA protocol that provides Authentication (verifying user credentials), Authorization (determining what the authenticated user is permitted to do), and Accounting (tracking resource usage, session duration, and activity for billing and auditing purposes). The three A's in RADIUS are Authentication, Authorization, and Accounting - not 'Auditing.' Option A replaces Accounting with Availability (incorrect). Option B uses 'Auditing' instead of Accounting (Accounting is the RADIUS term). Option C drops Authorization entirely. Option D correctly lists all three RADIUS AAA functions.
