The correct answer is D. Trust vs. mistrust

Explanation:

During the first year of life, an infant will start to develop trust or mistrust in others. According to Erikson's Psychosocial Stages,  during this first stage the child becomes aware with the way his/her demands are being met by the primary caregiver. During this age, a baby is completely dependent on the caregiver, thus he/she relies on him completely to have all his/her demands met. The way in which the caregiver(s) convey this trust or mistrust shapes the infant to successfully or unsuccessfully fulfil this first stage.
