Answer:
C - Peacemaking.
Explanation:
Peacemaking is a type of conflict approach that values the balance of different powers (mutual interests, capabilities, wills, etc) in a relationship. What John is doing with this approach, by keeping his emotions in check, is a sort off negociation to avoid a breakdown of what she wants or can or will do. Therefore, he is trying to balance the relationship: given that skydiving is too dangerous, he tries to find new things for her to explore.
