Answer: C. Secure attachment to romantic partners in adulthood.
The style of attachment developed by an infant during childhood is capable of affecting adult relationships in the long run. During infancy, the type of relationship developed with your caregiver, guardian, or parent is a major determinant in the manner of approach you as an adult would use in handling relationship issues especially with a romantic partner.
Having an insecure attachment during infancy will lead to difficulty in handling or understanding the emotions and feelings of others. During infancy, frightening inconsistent, and confusing communication will lead to unsuccessful and equally insecure attachment with other adults.
