Besides a person's picture on their ID, what else can change often?

In the context of identification documents such as driver's licenses or state IDs, the information that tends to change most frequently is a person's address. Individuals move residences for numerous reasons, including personal, professional, or family circumstances, which necessitates updating their address on official identification.

While a person's name can change due to marriage or legal reasons, such occurrences are less frequent compared to changes in address. A license number is generally a unique identifier that remains constant throughout a person's lifetime and does not change unless there are specific circumstances such as a new issuance due to a serious infraction. The date of birth is a fixed point of data that remains unchanged after it is established upon birth and does not alter with life events. Thus, the most variable piece of information among these is the address, making it the correct choice.
