Selected Answer: C
C. The SMS OTP is more likely to be intercepted and lead to unauthorized disclosure of the code than the TOTP method. The main reason why the SMS OTP (One-Time Password) method is considered more risky compared to the TOTP (Time-Based One-Time Password) method is that SMS messages can be intercepted more easily. SMS messages can be vulnerable to interception through various methods, such as SIM swapping, man-in-the-middle attacks, or by exploiting vulnerabilities in the mobile network.
