Why each option
Smart cards are physical hardware tokens that store a digital certificate used to authenticate a user to systems and networks.
A biometric scanner reads a physical characteristic such as a fingerprint for identification but does not store or present a digital certificate.
A soft token is a software-based application that generates time-based one-time passwords (TOTP) and does not store or use a certificate for authentication.
A smart card is an ISO/IEC 7816-compliant physical card containing an embedded microchip that securely stores a digital certificate and its associated private key. When inserted into a card reader, it presents the certificate for authentication without exposing the private key, making it the correct answer for a device that stores a certificate used for authentication.
An OTP token is a hardware device that generates one-time passwords, which are used for authentication but are not certificate-based.
