Final answer:
Erik Erikson's psychosocial development theory suggests that infants with unmet needs likely develop trust issues, viewing the world as unpredictable with feelings of anxiety, fear, and mistrust.
Step-by-step explanation:
According to Erik Erikson's theory of psychosocial development, an infant whose needs are not met is likely to develop trust issues. The first stage, trust versus mistrust, is critical for infants (birth to 12 months) as they are completely dependent on their caregivers.
A responsive caregiver helps an infant develop trust, viewing the world as safe and predictable, whereas an unresponsive caregiver who fails to meet the infant's needs may cause the infant to see the world as unpredictable, cultivating feelings of anxiety, fear, and mistrust. Therefore, the correct answer is a) Trust issues.
