Final answer:
Marla is experiencing incongruence, which is a significant mismatch between one's self-concept and the perceptions of others, leading to possible reduced self-worth and psychological stress.
Step-by-step explanation:
According to Carl Rogers's theory in the humanistic approach to personality, what Marla is experiencing when there is a significant gap between her self-concept (how she views herself) and the feedback from her job evaluations (how others view her) is known as incongruence. This discrepancy can lead to feelings of confusion and stress because there is a mismatch between her ideal self, which is industrious and cooperative, and her actual self, as perceived by her peers. High levels of incongruence can negatively impact a person's self-worth and overall psychological wellbeing.
The correct answer to the question is d. incongruence.
