Answer: The answer is a). Trust vs mistrust
Explanation: Trust vs. mistrust is the first stage in Erik Erikson's theory of psychosocial development. This stage begins at birth and lasts through approximately 18 months of age. It is the most important period in a person's life because it shapes our view of the world, as well as our personalities. Infants learn to trust that their caregivers will meet their basic needs. If these needs are not consistently met, mistrust, suspicion, and anxiety may develop.
