Socialization primarily affects which part of the self?

According to George Herbert Mead's theory of the self, socialization profoundly affects both the "I" and the "Me." The "I" represents the spontaneous, unsocialized, and impulsive aspect of the self, while the "Me" is the socialized self, formed through internalizing societal attitudes and expectations. Socialization is the continuous process through which individuals learn to navigate social norms, developing their "Me" in response to others, which in turn influences the "I"'s reactions. Therefore, "I and Me" is the correct answer, as both components are shaped by social interaction. Options A and B are incomplete, as the self is a dynamic interplay of both. Option D is irrelevant.
