The correct choice is interdependence, which describes a mutual reliance between individuals where both parties contribute to each other's well-being. In the case of Ursula and Barry, their regular exchanges of help signify a balanced relationship where both individuals enhance each other's lives through their interactions. This mutual support fosters a connection that is essential for personal growth and resilience, characteristic of interdependency.

Other options might describe relationships differently. Dependence implies that one person leans heavily on the other for support, which may not capture the reciprocal nature of Ursula and Barry’s relationship. Social intimacy involves a deep emotional closeness that may not be indicated solely by the act of helping one another. Belonging refers to a sense of fitting in within a group or community, which, while significant, doesn't directly reflect the mutual assistance exchanged between Ursula and Barry. Thus, interdependence most accurately represents their dynamic.
