Answer: D

Explanation:

Multifactor authentication refers to the use of two or more different factors to verify an individual’s identity. In this case, using a smart card (something you have) and a PIN (something you know) constitutes multifactor authentication. Combining something you have and something you know adds an extra layer of security compared to using only one factor.
