The Correct Answer and Explanation is : Conflict theorists argue that inequality within the family arises from the competition for resources, such as time, money, and attention. Within a family, these resources are often distributed unevenly based on power dynamics, which can be influenced by gender, age, or societal expectations. For example, parents typically control
