Answer:

c. Two-factor authentication

Explanation:

Two-factor authentication is also known as 2FA. It is an extra form of security put in place aside the use of username and password to ensure the authenticity of someone trying to access an online platform with a registered account.

First the user enters his or her username and password, then they will also have to provide some extra information before finally gaining access. Such information could be ones place of birth, name of pet, something one has or know, etc.
