Devin Claims That She Does Not Have Any Negative Stereotypes

Devin claims that she does not have any negative stereotypes about women. But last week, when she called a technician to help her with a problem she was having with her computer, and the technician turned out to be a woman, a negative thought flashed through Devin's mind before she could stop herself ("Oh no," she thought, "a woman! A woman won't be able to help me with my problem!") . Devin surprised herself with this thought, and immediately tried to suppress it. What was going on here?

A) Devin's deliberate system was engaging in stereotyping.
B) Devin's deliberate system was engaging in prejudice.
C) Devin was showing a weak delay of gratification.
D) Devin's deliberate and automatic systems were "thinking" different things.
