Answer:
According to the object relations theorists, the option that becomes a model for all close adult relationships is Option 1: Mother-child relationship. This is because object relations theory emphasizes the importance of the early attachment bond between the infant and the primary caregiver, usually the mother, as the foundation for later personality development and interpersonal relations12. The mother-child relationship provides the infant with a sense of security, trust, and love, as well as a prototype for how to relate to others in terms of intimacy, empathy, and conflict resolution34. The quality of the mother-child relationship also influences the child’s self-image, self-esteem, and sense of identity34. Therefore, object relations theorists believe that the mother-child relationship becomes a model for all close adult relationships, such as friendships, romantic partnerships, and family ties.
