'Security token' is the correct answer because it is a physical device that the user possesses and uses to gain access to an information system or secure area. In the context of multifactor authentication, 'something you have' refers to a physical object the user must possess, such as a smart card, a hardware token, or a phone with an OTP app. The incorrect options 'Fingerprint' and 'Password' are 'something you are' and 'something you know' factors, respectively, which do not fit the 'something you have' category. 'Voice recognition' is part of biometric authentication, which also falls under 'something you are' since it uses your unique biological characteristics for identification.
