Step-by-step explanation:
In terms of adult attachment styles, insecure individuals seem to be possessive and jealous, while avoidant individuals are less invested in relationships and more likely to leave them. Therefore, the correct answer is B. insecure; avoidant. Attachment styles, as developed by Mary Ainsworth and later by other researchers, describe the patterns of attachment that continue into adulthood. Insecure attachment typically leads to issues such as jealousy and possessiveness in relationships. On the other hand, those with an avoidant attachment style might not see relationships as essential, keeping an emotional distance, and thus, may exit relationships more easily.The main answer to the related question regarding the child's use of the parent as a base from which to explore the world is secure attachment. Children with secure attachment show signs of distress when separated from their caregivers but are able to be comforted upon reunion, indicating a healthy attachment that serves as a foundation for future relationship building.
