Since the Day Ben Met Sandra at Work, He Has

Since the day Ben met Sandra at work, he has not liked her. Ben has always thought Sandra was arrogant and rude, especially towards him. As Ben sees Sandra every day at work, he has been reminded over and over again of how arrogant and rude she is. Sandra found out what Ben thought of her, and made a conscious effort to act nicer to Ben, and also towards others around the office. Although others have noticed that Sandra has changed remarkably for the better since she started working there, Ben cannot see this and maintains his negative perception of Sandra. Ben's attitude towards Sandra demonstrates that:

A) the accessibility of attitudes can produce insensitivity to change.
B) there is a clear attitude-behaviour link.
C) Ben's negative evaluations of Sandra are unjustified.
D) all attitudes can never be changed, regardless of people's best efforts.
