Which of the following would meet the requirements for multifactor authentication?

This combination only utilizes factors from the 'something you know' category (PIN and employee ID), failing to incorporate at least two different factor types required for true multifactor authentication.

This option combines a biometric factor ('something you are' - fingerprint) with a knowledge factor ('something you know' - password). By using distinct types of authentication factors, it successfully satisfies the requirements for multifactor authentication.

Both a smart card and a hardware token fall under the 'something you have' authentication factor, thus not providing two distinct types of factors for multifactor authentication.

Both voice recognition and retina scan are biometric factors, falling under the 'something you are' category, which means this combination does not provide distinct authentication factor types.
