Why each option
To implement two-factor authentication, a second, distinct authentication factor must be added to the existing username and password. A smart card provides the 'something you have' factor necessary to achieve this goal.
A PIN is a 'something you know' factor, which, when combined with a password, still only constitutes a single authentication factor type.
A security question is also a 'something you know' factor, and does not introduce a second, distinct type of authentication factor.
A smart card represents the 'something you have' authentication factor. When combined with a PIN or password (the 'something you know' factor) to unlock its credentials, it provides two distinct factors. This combination achieves two-factor authentication by requiring two different categories of proof of identity.
A passphrase is an extended form of a password and falls under the 'something you know' category, thus not providing a second authentication factor type.
A CAPTCHA is a mechanism to verify that a user is human and is not considered an authentication factor for identity verification.
