Answer: The correct answer is D. Affective.
Explanation: The affective component of an attitude refers to all of the emotions and feelings about the object of attitude. The affective component is how individuals feel about things, how they feel when presented to a certain stimulus, what emotions do they experience when in certain situations.
In this particular example, Sally doesn't complain to a man smoking in the nonsmoking section because she is neutral toward people smoking in restaurants, she doesn't feel any emotion in particular if she sees someone smoking, therefore in that particular situation the lack of irritation reflects the affective component of her attitude.
The correct answer is D. Affective.
