Answer:
a. autonomy/connection
Step-by-step explanation:
Relationship dialectic theory is a theory that explains communication patterns that arise between individuals when they maintain a relationship focusing on tensions and struggles in a relationship.
Internal dialectics refers to the tensions that arise within the couple while external dialectics refers to the tensions that arise between the couple and society.
One type of internal dialectic is the autonomy/connection dialectic, in this one, the individual feels a contradiction between the desire of being close to their partner and spend time together and the desire of maintain a feeling of independence and autonomy.
In this example, Nick wants to spend time with David but he also doesn't want to lose his feeling of independence, he is experiencing a conflict between his desire of being close to David and his desire of maintaining a feeling of independence. Thus, Nick is struggling with the autonomy/connection dialectic.
