B Correct answer
Explanation

Multi-factor authentication uses two or more independent categories: something you know (password), something you have (token), something you are (biometric). This question describes the combination of knowledge and possession factors. Passwords (A) are one factor, credentials (C) are the authentication data itself, and identities (D) are who is being authenticated.

AI explanation

Authentication is commonly built from three categories, or 'factors': something you know (a password/PIN), something you have (a token or smart card), and something you are (a biometric trait). Combining two different factors — like a password plus a hardware token — is what makes multi-factor authentication stronger than any single factor alone. 'Passwords' and 'Credentials' are examples within a factor, not the name for the category itself.
