Answer: B

Explanation:

References: Federation with Active Directory Federation Services (AD FS) is required to allow users to sign in by using smart card-based certificates.

Federated authentication

When you choose this authentication method, Azure AD hands off the authentication process to a separate trusted authentication system, such as on-premises Active Directory Federation Services (AD FS), to validate the user’s password.

The authentication system can provide additional advanced authentication requirements.

Examples are smartcard-based authentication or third-party multifactor authentication.
