Answer:
a. through interaction with others
Explanation:
In psychology, the term self refers to the idea we have of ourselves including our abilities, skills and how we feel about them. In other words, it refers to the idea that we have about ourselves.
There are many theories about how the self is formed (starting from Freud's psychoanalytic view) but they all agree that the image we have of ourselves is constructed based on the the interactions we have with other people and the feedback we receive from them plays a crucial role in the idea we have of ourselves. In other words, the self ends up developing through the influence of the environment and the people around us.
Therefore, the self is formed a.through interaction with others.
