Explanation

Despite presenting three pieces of information, this is Single Factor Authentication (C). Multifactor authentication (MFA) requires credentials from two or more different factor categories: something you know, something you have, and something you are. Here, all three items - username, password, and the pre-mailed four-digit PIN - are 'something you know.' A static PIN mailed during registration and then memorized/stored is a knowledge factor, not a possession factor (which would require a physical token generating a real-time code). Because all credentials come from the same category, only one factor type is being verified, making this single-factor despite having multiple credentials.
