How I view my character actually reallly just depends on the current situation the character is in:

If socializing with other players (Except those that may be RPing) I would tend to go B, since I interect with others much the same way I do IRL (Minus gut-punching and eye-pocking and midget punting... okay maybe gut-punching and replace eye-poking with forehead-flicking).

While viewing cutscenes I tend to imagine my character as C. But usually I associate my character as the typical silent-hero archetype that's around so many games, I still grow attached to it (especially after the last grand company quest in 1.0, I clapped as well for my char :P).

And while in combat that's not story driven and is more for aesthetic purposes (Dungeon runs, Levequests, etc.) I go D... where my character is imagined as an ACTION FIGURE WITH COOL SPECIAL EFFECTS THAT LIGHT UP (Batteries not included).
