Answer options

• A. 3-factor authentication
• B. Proactive authentication
• C. 2-factor authentication

Correct answer: C

Explanation

The correct answer is C, 2-factor authentication, as it specifically refers to the use of two different forms of verification: something you know (username and password) and something you have (the code from the authentication app). Option A, 3-factor authentication, includes an additional verification method, which is not applicable here. The other options do not accurately represent the combination of factors involved in this process.
