Answer:
B - in conscious awareness; involuntary and sometimes unconscious.
Step-by-step explanation:
As the exercise briefly details, explicit attitudes are attitudes that reside on the conscious level whereas the implicit are those that are involuntary formed, that reside at the unconscious level, that are unknown to us. For example, out of a given choice of snacks, with time to pick, if one knows that likes ice cream the most, the explicit choice would be to pick it instead of something else. An implicit attitude would be spontaneous and difficult to control.
