Which principle of animation deals with imparting a unique identity to the animated character?

In this question, it's basically asking which of the 12 principles of animation make the character different from others.

Based on the 12 principles of animation, feels like all of them, should make the animated character different than others. Or specifically, in this question, I think the answer should be:

Anticipation.

Because, Anticipation is used in animation to set the audience up for an action that is about to happen. An easy way to think about this is that if a person needs to move forward, they first must move back. For example, if a character is about to walk forward, they might move back slightly, this not only gets their momentum up, but it also lets the audience know this person is about to move. Or if a character is reaching for a glass on a table, they might move their hand back, before moving it forward. Not only is anticipation needed to prepare the audience, but it's also required to sell believable movements. For example, before a baseball player pitches they first need to move their entire body and arm back to gain enough energy, and before a parkour enthusiast leaps of a ledge they first must bend their knees to prepare for the jump. Imagine if these actions had no anticipation - they wouldn't be believable.

Means create character actions based on personality. Which I think is the most important principle in 12 of them.
