"Something you do" is one of the three types of authentication factors used in multi-factor authentication. It refers to a unique behavioral or physiological characteristic of an individual, which cannot be easily replicated or forged. The following options are given to identify the two considered as something you do.

A. Iris scan - This option is considered as "something you are" authentication factor, which refers to physiological characteristics of an individual. In the case of iris scan, the unique pattern of an individual's iris is scanned and matched with the previously enrolled pattern for authentication.

B. Handwriting - This option is considered as "something you do" authentication factor, which refers to behavioral characteristics of an individual. In the case of handwriting, the unique way an individual writes or signs is analyzed and compared with previously enrolled handwriting samples for authentication.

C. CAC card - This option is considered as "something you have" authentication factor, which refers to possession or ownership of an object. In the case of CAC card, it is a physical smart card that contains a user's digital certificate, which can be used for authentication purposes.

D. Gait - This option is considered as "something you do" authentication factor, which refers to behavioral characteristics of an individual. In the case of gait, the unique way an individual walks or moves is analyzed and compared with previously enrolled gait patterns for authentication.
