Why each option

FortiGate supports FortiToken, email, and SMS phone messages as methods to deliver the token code for two-factor authentication.

ABrowser pop-up window.

A browser pop-up window is part of the authentication interface for entering a token, not a method for delivering the token code itself.

BFortiToken.Correct

FortiToken refers to the Fortinet proprietary hardware tokens or software application (FortiToken Mobile) that generate time-based one-time passwords (TOTP) for authentication.

CEmail.Correct

FortiGate can be configured to send a one-time password (OTP) to a user's registered email address as part of the two-factor authentication process.

DCode books.

Code books, which involve pre-printed lists of codes, are an outdated and generally unsupported method for two-factor authentication on FortiGate compared to dynamic methods.

ESMS phone message.Correct

FortiGate can be configured to send an OTP via an SMS text message to a user's registered phone number for two-factor authentication.
