Ego integrity relies on ______.

A) need to make amends for past mistakes
B) emotional responses
C) need for concrete reasoning
D) dialectical reasoning

Ego integrity requires the ability to engage in dialectical reasoning, which involves being able to see multiple perspectives and hold opposing ideas simultaneously. This allows individuals to integrate the positive and negative aspects of their life experiences, leading to a sense of wholeness and acceptance of one's life as a whole. The other options, such as needing to make amends or relying on emotional responses, do not capture the essence of ego integrity.
