The correct answer is C. RSA token. An RSA token is the most commonly used second factor in two-factor authentication alongside a password, generating a time-based one-time passcode that must be entered to verify identity.

Why each option
An RSA token is the most commonly used second factor in two-factor authentication alongside a password, generating a time-based one-time passcode that must be entered to verify identity.
A retinal scanner is a biometric device that could serve as a second factor, but it is expensive specialized hardware and is not commonly deployed as a standard second factor alongside passwords in most organizations.
A key lock is a physical access control device for securing hardware and is not a mechanism for authenticating user identity in a computer login context.
An RSA SecurID token (hardware or software) generates a new numeric code every 30 or 60 seconds using a time-based algorithm synchronized with the authentication server. After entering their password (something they know), the user also enters the current token code (something they have), fulfilling the two-factor requirement. RSA tokens are widely deployed in enterprise environments as a proven, dedicated second-factor mechanism.
A privacy filter is a physical screen overlay that limits viewing angles to protect against visual eavesdropping and plays no role in authentication.
