Question

which of these probably could not be used to identify you without additional information?
a. your username and password for a banking website
b. your full name
c. a list of your favorite movies
d. your home phone number

Explanation:

A list of favorite movies is too general and common. Many people can have the same favorite movies. While a username and password (A) is unique to an individual for that banking website, a full name (B) (even though there can be duplicates, often with additional info like address etc. it can identify), and a home phone number (D) (is unique per household usually) can be used for identification. A list of favorite movies (C) lacks the uniqueness and specificity without more context to identify a particular person.

Answer:

C. A list of your favorite movies
