Answer:
The correct answer is letter d) trust vs. mistrust.
Explanation:
Trust vs. mistrust is the very first stage in the psychosocial development theory by Erik Erikson. From ages 0 to 18 months, children rely on their caregivers to give them a sense of reliability, predictability, and consistency, which will allow children to develop trust. Children are very uncertain of the world when at this stage, so the caregiver is their source of stability. When children do not encounter such characteristics, they develop anxiety, mistrust, and suspicion.
