Why each option
In multifactor authentication, 'something you have' refers to a physical object in a user's possession, and an ID card is the only possession-based factor among the choices.
A password is a 'something you know' factor because it is a memorized secret, not a physical object the user carries.
A PIN is also a 'something you know' factor, as it is a memorized numeric credential rather than a physical possession.
A fingerprint is a 'something you are' (inherence) factor, representing a biometric characteristic intrinsic to the individual's body.
An ID card is a physical token that the user must possess and present, placing it squarely in the 'something you have' category of MFA. Possession factors require the authenticating party to physically carry or hold the item, which distinguishes them from knowledge factors such as passwords and inherence factors such as biometrics.
