The correct answer is A. Multifactor. This is an example of Multifactor Authentication (MFA). MFA requires two or more verification factors from different categories: something you know (login credentials), something you have (the phone receiving the SMS code), or something you are (biometrics).

Explanation

This is an example of Multifactor Authentication (MFA). MFA requires two or more verification factors from different categories: something you know (login credentials), something you have (the phone receiving the SMS code), or something you are (biometrics). Here, the user provides credentials (factor 1) and a one-time SMS code (factor 2). RADIUS and TACACS are AAA (Authentication, Authorization, Accounting) protocols used by network devices to authenticate users against a central server - they are protocols, not authentication types. Kerberos is a ticket-based authentication protocol used in domain environments. None of the other choices describe the two-step verification process shown in this scenario.
