Final answer:
Responsive caregiving is likely to produce securely attached infants, as it provides consistency, emotional availability, and a secure base for children to explore the world.
Step-by-step explanation:
The question asks about the caregiving style that is likely to produce securely attached human infants. According to attachment theory research, particularly the work of Ainsworth and Bell, securely attached children are those whose caregivers are responsive and sensitive to their needs. These children see their caregivers as a secure base from which to explore and seek out in times of stress. The correct answer is c) Responsive caregiving. Responsive caregivers provide consistent care and emotional availability, allowing children to develop trust and a sense of the world as a safe and predictable place, in line with Erikson's trust versus mistrust stage of development.
