While Layne's Friends Enjoy Her Sense of Humour and Warmth

While Layne's friends enjoy her sense of humour and warmth, they are often frustrated by her inability to arrive at places on time. Worse, she rarely calls to say she will be late, and sometimes she doesn't show up at all. She hates to commit to anything beforehand and seems to make decisions based on her moods, regardless of how her behaviour might affect others. Based on this information and relying on the five-factor model, we can say that Layne would be most likely to score low in

A) agreeableness.
B) neuroticism.
C) openness.
D) conscientiousness.
