Final Answer : C, Explanation :  Personality is shaped by a complex interplay between genetic and environmental factors. While siblings growing up in the same family environment may share many experiences, they also have unique experiences and relationships that can shape their personalities in different ways. This is known as the nonshared environment, which can include differences in parenting, peer relationships, and life events. As a result, it is quite common for siblings to have different personalities despite being raised in the same home environment.
