Explanation

TACACS+ separates the three AAA functions - Authentication, Authorization, and Accounting - into independent, modular processes, allowing granular control over each function independently. RADIUS combines authentication and authorization into a single exchange (the Access-Accept response carries both authentication results and authorization attributes simultaneously). Additionally, TACACS+ uses TCP for reliable transport while RADIUS uses UDP; TACACS+ encrypts the entire packet payload while RADIUS only encrypts the password field; and RADIUS supports multiple network layer protocols while TACACS+ was originally IP-centric. Answer B correctly identifies the key architectural difference.
